Types Heat map

a heat map, atop color bathymetric map, indicating probable location of missing malaysia airlines flight 370 based on bayesian method analysis of possible flight paths of aircraft.

there different kinds of heat maps:

web heat maps have been used displaying areas of web page scanned visitors. web heatmaps used alongside other forms of web analytics , session replay tools.
biology heat maps typically used in molecular biology represent level of expression of many genes across number of comparable samples (e.g. cells in different states, samples different patients) obtained dna microarrays.
the tree map 2d hierarchical partitioning of data visually resembles heat map.
a mosaic plot tiled heat map representing two-way or higher-way table of data. treemaps, rectangular regions in mosaic plot hierarchically organized. means regions rectangles instead of squares. friendly (1994) surveys history , usage of graph.
a density function visualization heat map representing density of dots in map. enables 1 perceive density of points independently of zoom factor. perrot et al (2015) proposed way use density function visualize billions of dots using big data infrastructure spark , hadoop.
