Heatmap.Js - A JavaScript Library That Can Be Used To Generate Web Heatmaps With The HTML5Canvas Element

Heatmap.js is a JavaScript library that can be used to generate web heatmaps with the html5canvas element based on your data. Heatmap instances contain a store in order to colorize the heatmap based on relative data, which means if you're adding only a single datapoint to the store it will be displayed as the hottest(red) spot, then adding another point with a higher count, it will dynamically recalculate.
