Heatmap representation. A heatmap representation is displayed as a map, with gene and cell-type axes implemented in Protovis attached at right and bottom. The axes are linked to the map’s zooming and panning so that users can identify which genes and cells they are looking at. Selection of an area of interest prompts the highlighting of the corresponding cell types and genes.
