Submitting Changes

Either send an email to Jeff ([email protected]) or send a Pull Request.

If you're making a pull request, the process is:

1. Update dances.json with your change. The structure of each record is: [url, city, weekdays, annual frequency, gender free?, active?],

   For example: ["http://www.bidadance.org/", "Cambridge MA", "Sundays", 21, "GF", true],

   Note that annual frequencies are just guesses, and currently many of them are too high because of dances resuming with fewer annual events than before the pandemic.

2. Run ./lookup_locs.py to update dances_locs.json with your changes and pull in latitude and longitude.

3. Commit your changes and make a PR.

Structure

• index.html: main page, containing both the display and the scripts.
• dances.json: dance database.
• dances_locs.json: dance database with locations automatically added.
• zipcode.json: giant map from zipcode to lat/lng.

Updating zipcode.json

You can get the initial CSV from anywhere, but I found this one easy: http://www.unitedstateszipcodes.org/zip-code-database/

Once you have the .csv you can run:

python build_zipcode_json.py <csv-file>
