Unlike charts where interpretation is required and tables where understanding is paramount, heat maps are self-explanatory and intuitive. It is used to cross-examine multivariate data. The JavaScript Heat map in ApexCharts uses bright-to-dull color spectrums to demonstrate which portion of a plot/page receives more attention than the other. The visualized datasets may differ in hue, shade, or intensity so that users and data analysts can more easily read and understand how the values vary across time.
