Tableau Heat Map
The heat map is used to visualize the data in the form of size and color on different measures.
Two different measures are visualized simultaneously using a heat map. One measure is assigned to size, whereas another measure is attached to the color of the heat map.
For example, consider the data source such as the Sample-Superstore and its dimensions and measures.
