This is a 2020 refresh of the Charter Campuses map completed for RYHT in 2019, below is the original README
Interactive map showing the expansion of charter campuses over time in Texas
Loading the data for the line chart is liable to fail because of https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors/CORSRequestNotHttp . If the chart doesn't display, then we have at least two options:
- Put code on github.io and test there
- Run a local web server
Setting up a local server should be easy with Python. Simply open a command line window, go to this folder, type python -m SimpleHTTPServer 1883 (for Python 2) or python -m http.server 1883 (for Python 3) or python3 -m http.server 1883 (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:1883/ (of course you can change the number).
Exactly where to edit options for the chart can be a bit confusing, so here's a primer:
Text positioning: this is set by various .attr(...) lines in the drawChart() function in the function.js file in /scripts, so that it can position everything relative to the size of the chart area.
Y axis label colours: these are defined by the chartData object in the function.js file in /scripts. This is done here because that's the easiest way to have a single place to edit which controls labels and line colours together.
Which data series are loaded by default: same chartData object as above.
Text sizes and styling: look for rules starting with #chart in the CSS, except for the Y axis label colours.
