Rebranding and other updates to the Raise Your Hand Texas Programs Map
Google sheets CORS rules seem to have started blocking requests from file:// URLs. So to preview this on our local machines we need to run a server. An easy way to do that is:
Open a command line window, go to this folder, type python -m SimpleHTTPServer 2023 (for Python 2) or python -m http.server 2023 (for Python 3) or python3 -m http.server 2023 (to explicitly select Python3 in an environment that also has Python 2 installed), and leave that session running.
Then the page should be available at http://localhost:2023/ (you can change the number in the python command to also change it in the localhost URL).
The min, max, and default starting years for the time slider are set in the <input id='slider'> declaration in index.html itself. All other references take their values from what is set there.
