SF Election Results Processor/Viewer

This repo contains two elements:

  • A node app that processes SF election data, matching ballots with precinct shapes
  • A simple viewer web app, built in Vue, which displays the aforementioned data.

Note that this web app only calculates first-choice votes, not ranked votes.

Also, thanks to dbaron/sf-elections-rcv which I referenced in making this.

Instructions for processing and viewing election data

  1. Run npm install in the processor directory to install dependencies.

  2. Get an election JSON zip file ready. You can get them at the SF Elections website.

  3. You may want to make sure your precinct shape geojson is up-to-date. It's included here as precincts.geojson in the processor directory. I got this from DataSF – just click "Export", then select "GeoJSON."

  4. Run node index.js ./dir/to/election_data.zip and wait

  5. Place output.json in the data sub-directory in the viewer directory as 11-05-19.json`` – you may change this filename in main.js```.

  6. To run the viewer locally, you'll just need a simple server running. For example, on macOS, head to the viewer directory in Terminal and run python -m SimpleHTTPServer 8080 and you'll be able to view the web app at http://0.0.0.0:8080 in your browser.
