WHAT IS A HEATMAP?
A heat map is a type of data visualization that use color to convey data points in a simple format. The shade of color in a heat map typically indicates the volume of a data point. In a heatmap, relationships between two variables (one plotted on each axis) are displayed. By observing how cell colors change across each axis,cell colorings can correspond to all manner of metrics.
WHEN TO USE HEATMAPS?
Heatmaps are ideal when you need to indicate the categorical variable's value in the corresponding cell range by each cell's color.
