What is a heatmap?

A heatmap is a visualization used for visualizing three dimensional data. Two dimensions represent cartesian coordinates (x and y values) and the third dimension is used for showing the intensity of a datapoint in relative comparison to the absolute maximum of the dataset. The intensity is shown as a color, usually red (hot) is used for the maxima and blue (cold) for minima.

heatmap.js' purpose

heatmap.js lets you easily create web heatmaps with JavaScript. The heatmaps are fully customizable - feel free to choose your own color gradient, change the opacity, datapoint radius and many more. Use it for A/B testing, visualizing map data or for whatever pops into your mind :)
