This is a tool for deciding when to swim at San Francisco public pools.
First run generate.py to gather pool swim times from sfrecpark.org and output the html file index.html. This page contains all the data and provides some simple filtering.
You could then run a local web server (for example 'python -m SimpleHTTPServer 8000') to serve up the html and javascript. The most recent version is also served at https://sfrec.info/
To run the python script you'll need Python 3.x and BeautifulSoup4.
