What is heatmap and its use cases?

< 1 min read

A heatmap is a visual that uses color intensity to represent data values.
It helps identify patterns, concentration, and performance variations quickly.
Darker or stronger colors usually indicate higher values.
In one project, I created a heatmap to show sales performance by region and month.
It helped management quickly spot low-performing months in specific regions.
Heatmaps are useful for large datasets with two dimensions.
They work well for performance tracking and variance analysis.
They provide quick visual insight without reading detailed numbers.
