Heatmap of changes in stock prices
uses d3js for heatmap (treemap)
uses Polygon API, MySQL, PHP at back-end
This was made as a project for my college. They had requirements to all of {PHP, MySQL, JS}. I may refactor the design in the future.
I accidentally uploaded my API key to the repo. I was having some issues with environment variable in Fedora (seethe)
I renewed my API key from polygon (cope)
