It uses the power and flexibility of the HTML5 canvas element to draw heatmaps based on your data.
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.
