How to build a heatmap
No template to fill in and no drawing. You talk; the canvas keeps up.
02
Choose what color means
Specify whether color represents counts, percentages, or another measure. Request a legend with a stated minimum and maximum.

Check the comparisons
Match a few cells to the source table. Ask for a different ordering or scale if the current colors conceal useful differences.
What does a heatmap show?
A heatmap uses color to encode values at the intersections of two categories. It helps readers scan a grid for concentrations, gaps, and repeated patterns without comparing every number individually.
When a color grid is useful
Use a heatmap for activity by time, measurements across samples, or comparisons between categories. The example maps team activity by weekday and hour; it does not collect activity data itself.
Rules for readable heatmaps
- Name both dimensions. Readers should know what each row and column represents.
- Explain the measure. Put the unit and meaning of the values beside the legend.
- Keep scales comparable. Use the same limits when comparing multiple grids.
- Distinguish zero from missing. An unrecorded value is not evidence that nothing occurred.
- Choose a meaningful order. Keep time chronological and arrange categories to support the question.
How MyMap builds the grid
MyMap uses the data and categories in your prompt to draft a heatmap on the canvas. Ask it to label cells, change the category order, or use a shared scale across comparisons.

Common questions
Is this a website click-tracking tool?
No tracking setup is described here. Supply the values you want to visualize; a generated heatmap does not by itself measure clicks, visits, or user behavior.
Can I compare percentages and counts in one grid?
Use separate grids or convert values to a clearly explained common measure. A single color legend should not silently represent different units.
What if I only have a topic and no numbers?
Ask for a clearly labeled illustrative grid or provide a blank structure. Do not present generated sample values as observations.
