When should I trim the number of values?
Too many points overwhelm viewers. Keep x-axis labels readable and rumble the data into summary points when possible.
What Is a Geo Heat Map?
This chart turns structured data into a visual pattern that is faster to scan than a raw table.
Use it when the reader should understand shape, comparison, distribution, proportion, or movement quickly.
Start With the Raw Data
Most charts begin with a small, structured table before the visual layer is added:
| Label | Value A | Value B |
|---|---|---|
| Example 1 | 24 | 31 |
| Example 2 | 30 | 28 |
| Example 3 | 18 | 36 |
The raw values stay the same, but the visual structure makes patterns easier to spot: highs, lows, clusters, gaps, and unusual changes.
