Definition
A heatmap is a two-dimensional graphical representation of data where individual values are represented by colors. It allows viewers to quickly grasp complex information by mapping values onto color gradients, highlighting patterns or insights across various datasets.
Heatmap vs. Other Data Visualization Techniques
| Heatmap | Bar Chart |
|---|---|
| Representation | Uses colors to denote data values across two dimensions |
| Complexity | Can convey intricate data sets at a glance |
| Use Case | Ideal for analyzing user interactions on a website, demonstrating real estate price differences by location, or any data that can benefit from color gradation |
| Viewer Insight | Offers immediate analysis of patterns, making it fun and quickly digestible |
