• Clone this repo (themarshallproject/gfx-v2) into an appropriately named and located folder with this command: git clone [email protected]:themarshallproject/gfx-v2.git <project name>

• cd <project name>

• Run bash setup.sh

• Provide a slug that will uniquely identify this project. You do not need to append the date manually, the setup tool can do that for you. Please do append the date if you are creating a story specific graphic. Only general tools should be left date-less. (In the future it will be impossible to accidentally conflict with the slug of another project, but for now be careful of that!).

• Specify the type of project you are starting.

• Choose whether or not you want to automatically create a new GitHub repo for this project.

• Make stuff!

• Clone the project repository with git clone <repo url>
• Run bash setup.sh. (Hint: this is almost the same as just running npm install)
• Make stuff!

• Run gulp which will start the local server, and live-reload your changes.
• Edit files only inside of the src directory.
• To change post format, run gulp reset:type and then re-run gulp.

• Run gulp deploy to send files to S3 and EndRun.

• You will be prompted for credentials if you have not entered them before. You will need an AWS keypair, a Github API token, and an EndRun API key.

• The graphics rig uses modern JavaScript imports. Anything imported into graphic.js will be included in the page.

You can use a single repo to house multiple graphics and/or a custom header, and deploy them all at once. This is very useful for a post with multiple components. Or when you have several similar charts that would benefit from sharing CSS and/or JS.

By default, the src/ folder will contain a single html file: graphic.html. If you have more than one html file in src/, each html file will become its own graphic. The name of the file will be used to identify it in EndRun. The shortcode will take the form [graphic slug=<graphicreposlug>:<filename>].

When you are ready to deploy, if you are not using a custom hed, you have to manually add the asset include graphic in the post. This will be slugged <yourmainslug>:includes. Add it to the bottom of the post. The includes graphic allows us to load the project's JS and CSS once despite being shared across multiple graphics.

When you set up a project, you can choose "freeform header" as the graphic type. This will add a file called header.mustache into src/, which will be used to build your header. This mustache filetype will allow you to pull down actual post data from Endrun, like the post's headline and publish time. (Read more on this below.) If you'd prefer to hard-code everything, you can rename the file to header.html and just write standard html in it.

When you deploy, the file named header.mustache or header.html will appear at the top of the post. If you have additional graphics in the post, you do not need to include the includes graphic as above. The assets will be included in the header file.

When we develop custom headers, we often include information that is normally edited in or generated by Endrun (e.g. post headline, byline, publish time). To avoid having to manually update this information every time it changes, you can pull post data down from Endrun.

By default when you setup a project with the freeform header type, a file called header.mustache will be created in src/. This uses the Mustache templating engine to dynamically render html based on a json of post data. The file includes some boilerplate code for you to work off of, and pulls example data from post-templates/custom-header-data.json.

To download data from an actual post in Endrun, you'll want to first deploy your graphic to create a new post, or add the graphic slug to an existing post's "Internal Slug" field in the advanced post editor. Once the slug is associated with a specific post in Endrun, you can download metadata for that post by running gulp posts:download.

Take a look at post-templates/custom-header-data.json to see what fields are available to use in developing a custom header.

Some fields (byline, producer byline, social tools) will appear by default within the sidebar of an Endrun post. If you use those fields in your custom header and wish to hide the defaults that appear in the sidebar, you can hide the entire sidebar with .container article > aside.col4 { display: none; } or can choose to hide individual children within that container.

By default during local development each graphic is concatenated together (with a placeholder paragraph in between) in the template. You can customize the layout of the graphics in development by editing post-templates/localtext.md. This file is designed to work with the same stuff you would put into an EndRun post. You may, in fact, want to just paste in a semi-produced post, graphic shortcodes and all.

Your graphics will be placed according to where the graphic shortcodes appear in localtext.md. These shortcodes take the form of [graphic slug=<graphicreposlug>:<filename>]. So if you had a file named intro.html in a repo with the slug slugfest, the shortcode would [graphic slug=slugfest:intro].

Remember that you don't have to use localtext.md at all. A normal workflow might be leaving it empty while you develop prototypes of your various graphics, and then deploy and put them in a post. Then copy the produced post's contents back down to localtext.md, so that your graphics environment more closely resembles the real post.

You may want to use a data file such as a CSV or JSON to populate your HTML. The graphics rig makes any CSV or JSON files placed in src/template-files available to graphic.html to be accessed as JSON through templates written in the Nunjucks templating language.

For example, say you want to create a table. Rather than writing each row of the table HTML by hand, you could create a Nunjucks template for a table row and loop over a dataset to populate the table.

Let's say you have this CSV:

name,date,nickname
"New York","July 26, 1788","The Empire State"
"Florida","March 3, 1845","The Sunshine State"
"Hawaii","August 21, 1959","The Islands of Aloha"

To access it from the HTML, first save it to src/template-files. Let's say we save it down as src/template-files/states.csv.

In the graphic HTML, you can now reference a data object, where any files you've saved to src/template-files are now accessible as keys corresponding to their filename. So our states data can be accessed as data.states.

To build a table, you might write templating markup somewhat like this:

<table>
  <thead>
    <tr>
      <th>State</th>
      <th>Date admitted</th>
      <th>Nickname</th>
    </tr>
  </thead>
  <tbody>
    {% for row in data.states %}
    <tr>
      <td>{{ row.name }}</td>
      <td>{{ row.date }}</td>
      <td>{{ row.nickname }}</td>
    </tr>
    {% endfor %}
  </tbody>
</table>

The result should appear like this:

CSV files added to src/template-files are converted to JSON before being passed to the HTML template. There are three formatting options, depending on how your data is structured.

Array of objects

By default, data will be formatted as an array of objects, where each object corresponds to a row in the CSV and the object keys correspond to the CSV's column headers. For example, the states.csv file above would appear as:

[
  {
    "name": "New York",
    "date": "July 26, 1788",
    "nickname": "The Empire State"
  },
  {
    "name": "Florida",
    "date": "March 3, 1845",
    "nickname": "The Sunshine State"
  },
  {
    "name": "Hawaii",
    "date": "August 21, 1959",
    "nickname": "The Islands of Aloha"
  }
]

Keyed lookup

If you wish to access your data by key rather than as an array, just name the first column of your CSV key and use a unique value for each row.

A CSV formatted like this:

key,value,char_count
"Headline","Dewey defeats Truman",20
"Deck","G.O.P. Sweep Indicated in State",31
"Description","This is the text from the erroneous early edition of the Chicago Daily Tribune from Nov. 3, 1948.",97

will output like this:

{
  Headline: {
    key: "Headline",
    value: "Dewey defeats Truman",
    char_count: "20"
  },
  Deck: {
    key: "Deck",
    value: "G.O.P. Sweep Indicated in State",
    char_count: "31"
  },
  Description: {
    key: "Description",
    value: "This is the text from the erroneous early edition of the Chicago Daily Tribune from Nov. 3, 1948.",
    char_count: "97"
  }
}

Key-value pairs

Datasets that begin with a key column but only have two columns overall will be returned as an object of key-value pairs for ease of reference.

For example, removing the char_count column from our previous example CSV:

key,value
"Headline","Dewey defeats Truman"
"Deck","G.O.P. Sweep Indicated in State"
"Description","This is the text from the erroneous early edition of the Chicago Daily Tribune from Nov. 3, 1948."

would return a JSON like this:

{
  "Headline": "Dewey defeats Truman",
  "Deck": "G.O.P. Sweep Indicated in State",
  "Description": "This is the text from the erroneous early edition of the Chicago Daily Tribune from Nov. 3, 1948."
}

The above methods explain how to access data in src/template-files from your HTML. If you need to access that same data file from your JavaScript, you can find it in JSON format in assets/import-data.

For example, the file src/template-files/sports.csv will be converted to JSON and written to src/assets/import-data/sports.json. You can load it into your JavaScript however you like from there. For example:

fetch('assets/import-data/sports.json')
  .then((response) => response.json())
  .then((data) => {
    // Whatever you want from here
  })

The templates directory houses frequently used graphic formats and javascript modules for basic d3.js charts.

Our chart templates are javascript modules that can be used to create basic d3.js charts with configurable options. Documentation for the templates, including instructions for setup, can be found in the Chart Templates README.

If you build a graphic using ai2html, you can do so directly from within this rig. Copy the src folder from templates/ai2html into the base directory of this repo. Or use this command:

cp -r templates/ai2html/src .

After you've copied over the template, you can find an Illustrator template in src/ai2html/base-graphic.ai. Build your graphic here.

Once you're ready to see it on the page, run the src/ai2html/ai2html.js script and the output will automatically be dropped in the correct location at src/template-files/base-graphic.html. This file will be completely overwritten every time you run the ai2html script. The background images are placed in src/assets.

The ai2html output is imported into your main graphic.html file, so you can add additional HTML around your graphic without it being overwritten by the script.

In most cases, you can refer to the ai2html documentation from the New York Times graphics desk. However, we have one additional feature: constrained artboard widths.

Our ai2html template defaults to using "dynamic" responsive sizing -- that is, the graphic will always fill 100% of the width of its container. But sometimes this leads to graphics looking too stretched out. To constrain an artboard to a maximum width, you can add a data-constrain- attribute to the parent element in src/graphic.html.

For example, to constrain an artboard named "small" to stretch no more than 350px, your code would look like this:

  <div class="g-ai2html-wrapper" data-constrain-small="350">
    {% include "template-files/base-graphic.html" %}
  </div>

To do away with these constraints altogether, just remove the data-attributes from the parent.

It is possible to download google spreadsheets into local csv files. This can be helpful for projects with complex editorial-driven fields that will need to be frequently edited. Outside of this specific situation, you probably don't need this and should consider simpler solutions. To set it up, specify a spreadsheet_id, which is the long, alphanumeric string in the url of a google sheet. Next run gulp sheets:download, which will ask you for a series of credentials with links on where to find them (you'll need to be logged into your google account and have access to our google cloud console). Follow along with these instructions.

The client_secret.json identifies our 'app' and shouldn't ever change. The bearer token can expire. If it does, you might see an error like invalid_grant or something similar. To refresh this token you can run gulp credentials:google. If for some reason you do need to reset the client app credentials you should run gulp credentials:google_client.

Once you've been properly authorized (which you shouldn't need to do again for a good long while), the download task will convert each sheet of the spreadsheet into a separate csv file in src/template-files, using the name of the sheet as the name of the file. You can then import this data into your templates using the process described in using external data sources in your HTML.

• View examples of common graphics here, or check out the code in examples/.
• To build the example projects, run gulp build:examples.
• To add a new example to the page:
  • create a new directory in examples/ with a directory name that describes the graphic.
  • Place your html, javascript and sass inside. You can also include assets and external data, preserving the same folder structure that you'd use within src/.
  • You're good to go!

We can share graphics with partners by generating a code snippet that loads a graphic onto a partner's story page. The partner must have the ability to include inline javascript and html within their article.

To generate a graphic embed code, run gulp build:embed, which will set generate_external_embeds: true within your config.json. You only need to run this once. After that, any time you deploy your graphic, it will publish your assets and html to s3 and upload an embed code to Endrun. You can then find the embed snippet in the graphics admin in Endrun.

If you are embedding multiple graphics, you do not need to include a separate embed for script includes — they will be loaded by the embed code.

Embeds should not rely on any external javascript or CSS that is typically loaded on themarshallproject.org. To ensure that you aren't relying on any external code, you can preview your embeds at localhost:3000/embeds/.

If a partner can't publish inline javascript in their CMS, you can provide an iframe of a graphic. Getting one to send them can take a little bit of work, especially for multiple graphics setups, but it's doable.

1. A deployed graphic will be served to the public from https://www.themarshallproject.org/embed/graphic/<graphic-id> replacing <graphic-id> with your graphic's id, which you can find at https://www.themarshallproject.org/admin/graphics in the left-most column.
2. If everything works as expected at that url, skip to the last step. If not, it may because of some assumptions your code is making about the environment (fix these!) or it may be because you are using multiple graphics.
3. In multiple graphics setups the JS and CSS are bundled into a single package so they can be shared between all of the graphics. Each embedded graphic will need to individually include all of the assets it needs. The easiest solution to this is to add any script and style tags to an embed version of your graphic. Note that this is not as efficient as the way we do it within EndRun, so this should be a separate graphic with it's own slug/filename that is not included in the post. You can see an example of this setup here.
4. You can now send the iframe to the partner with some sample code like this: <iframe width="100%" height="900" src="https://www.themarshallproject.org/embed/graphic/<graphic-id>" frameborder="0"></iframe>, replacing the graphic id again.

Note that it is up to you to make sure your graphic is responsive, and works well within an iframe. It is up to the partner to make sure that the iframe is suitably sized and resizes dynamically, perhaps using a tool like NPR's pym.

When a project has data analysis associated with its graphic(s), you can include code for the source data, analysis, and output data in the analysis/ folder. You can also set up workflows to run your analysis from scratch using the Makefile. For example, make all would run the analysis workflow; make clean would remove all outputs from previous runs of the analysis; make deploy would upload data from the output_data/ folder onto S3 for sharing. See Makefile for more documentation of commands and to create your own analysis workflows.

• You can simplify the setup process a bit by creating a bash function to do the rote steps for you. Add this to your ~/.bashrc or equivalent:

function newgraphic() {
  git clone [email protected]:themarshallproject/gfx-v2.git $1
  cd $1
  bash setup.sh
}

Run source ~/.bashrc (or just open a new terminal session). Now you can create a new graphic with newgraphic <slug>, which will create the repo, put you in it, and then run setup.

• Similarly you can add this function (in the same place), to make the cloning of existing graphics a little easier. h/t @tommeagher

function clonegraphic() {
  git clone [email protected]:themarshallproject/$1.git
  cd $1
  bash setup.sh
}

• You can get the most recent version of this tool by running git pull updates master && npm install.

There are a few other commands available that you might find useful. Especially when working on developing this template. Review the bottom of gulpfile.js for a full accounting.

1. gulp reset:type will allow you to change your initial choices made while setting up the repo. Handy if you made a mistake, or are just rearranging things.
2. gulp credentials:endrun will allow to enter a fresh API token.
3. gulp credentials:github will allow you to enter a new personal Github access token when your old one expires.

Theoretically the graphics rig should be supported by any platform that supports node. In practice things are not always so simple. The most important difference is around credential management. We utilize the macOS 'keychain' for some added security on that platform. On other platforms we revert to plain-old text files. The graphics rig will create a credentials file for you if it doesn't already exist (defaults to .credentials.json in the project folder). However to get the mac-style credential memory between projects you need to take an additional step. To tell the rig where you want to store your system-wide credentials, set the CREDENTIALS_PATH environment variable in your .bashrc or equivalent. For example, I added this line to my bashrc:

export CREDENTIALS_PATH=~/.ssh/.credentials.json

(the ssh folder is convenient because it will already have appropriately restrictive permissions, but you can put it anywhere).

It's possible you may also run into some difficulties with the packages that require some compiled dependencies (notably node-sass). You're best bet is google, but feel free to ask around if you do run into trouble!

• Clone and push to a branch on this repo, then create a pull request.

• The setup process leaves behind a remote called updates. You can change this template by pushing commits there (git push updates master).

• In addition to the commands mentioned above, sometimes it is useful to edit this in conjunction with changes to EndRun. You can point deployments at a locally hosted EndRun by changing the endrun_host config parameter. Note that even if you do this, assets will still be uploaded to the real production s3 bucket, unless you also change the bucket parameter.
