going to be borrowing from Brian's implementation for this https://github.com/bhrutledge/ma-legislature/blob/main/index.html

Following up from a discussion with @bhinebaugh, I recommend "rebooting" Map.jsx with the code from https://github.com/bhrutledge/ma-legislature/, rather than trying to build on what's already there, which was based on https://github.com/actonmass/campaign-map. I spent a decent amount of time refactoring the actonmass code to support both chambers, and removed everything that was specific to that campaign.

Ideally, I think this would wait until @mvictor55 has a complete Google Sheet for one piece of legislation (i.e., ranking of support for both chambers), because that will impact how the data is loaded and transformed. However, in the interest of making progress, I think porting the ma-legislature code as-is would give a good base to build on. I'm optimistic that I could do it relatively quickly, but would happily let somebody else tackle it. If somebody else picks this up, I think familiarity with Leaflet is helpful, and I'm happy to review the PR.
