Viewing raw stats and tables only tell you part of a story.

Viz helps tell the rest of the story with interactive visualizations that are continually updated.

Viz is just getting started. Help spread the word!

Contributions and feedback are welcome.

Feel free to follow, star, fork, and check back for updates.

For the initial launch, the following visualizations and stats are available. Have an idea for a visualization or stat? Let us know!

Each dashboard within Viz offers different levels of interactivity. Try:

• Interacting with the filters.
• Hovering over elements to view tooltip info.
• Clicking elements to highlight or filter.

You can change the activate dashboard through the following control:

Yes, you'll need the free Reader. Download and run the latest Viz Workbook. This allows you to interact with a local copy--you'll need to download the latest workbook as updates are continually pushed.

Depending on your setup, you'll likely see improved performance running Viz locally.

Sessions timeout after some inactivity. For more details, view this post from the Tableau Forums.

The visualization hosting service might be having issues. Check the status.

You can also run Viz offline.

Although GitHub Trending is a great tool to discover up-and-coming projects, it only allows you to review up to one month of data. Third-party sites often show all-time stats that are relatively static, as they are dominated by well-established repos.

Viz is meant to supplement existing solutions by filtering only on the newest, most popular repos created within a specific timeframe.

For example, Viz 2015 will only track repos created within the year 2015.

For the initial launch, Viz provides stats for 2015.

Visualizations for 6-, 3-, and 1-month ranges are under development. The data for each range will be continually updated to keep Viz fresh.

In the future, Viz can be extended to track repos regardless of creation date. Feedback on this ticket is welcome.

Mining data directly from GitHub, Viz is powered by the GitHub API and leverages the following:

• github3.py to access the GitHub API through Python.
• pandas in the following IPython Notebook for data wrangling.
• Google Maps API through geocoder for location data.
• Tableau Public for visualizations.*

In the future, Google BigQuery along with GitHub Archive could also supplement the GitHub API.

The Viz 2015 stats were mined on January 1, 2016, between 00:00 to 01:00 PDT and include all repos created in the year 2015. The data is preserved here.

With GitHub Search, you can manually run queries similar to what you would get from the GitHub API.

To view the most-starred JavaScript repos created in 2015, run the following query:

created:2015-01-01..2015-12-31 stars:>=100 language:javascript

To check stats for a user's or an org's repos that were created in 2015, run:

created:2015-01-01..2015-12-31 stars:>=100 user:user_name

Star counts from the searches above will show data up to the time you performed the search.

Only repos with stars:>=100 are tracked to help filter GitHub's rapidly growing 30+ million repositories and to keep within the GitHub API rate limits.

Viz 6-, 3-, and 1-month might loosen this restriction as there should be less repos to analyze. Google BigQuery along with GitHub Archive could also supplement the GitHub API.

Viz provides stats for repos, users, and orgs by stars (and in many cases, forks). Stars and forks are not perfect metrics, yet they are simple and fairly effective measures of interest. For a more detailed discussion on measuring repo popularity, check out "On the Popularity of GitHub Applications: A Preliminary Note" which concludes:

The number of stars of a system tends to correlate not only with the number of forks, but also with its effective usage by other client applications, which reinforces the importance of stars as a real measure of a system’s popularity.

In the future, other stats such as issues, pull requests, followers, etc could be included.

To provide stats for users and orgs, Viz groups stars and forks by user or org. Note the stars:>=100 restriction still applies.

Viz tracks the most popular languages on GitHub plus the Unknown language option. Repo languages are identified by github/linguist.
