Heatmap encodes values as color value of a cell in a row-column grid. Toussaint Loua’s 1873 crime tables; later Toussaint/Bertin and 1990s gene arrays. In reports, ads and assignments it fits patterns across two categorical axes at once. Skip it when precise lookup of a number, or a rainbow that is not color-blind safe.
Excel or Google Sheets and PowerPoint share this geometry. Keep one claim per slide; export SVG or PDF rather than a screenshot. In Meta, Google and retail print, one number and one shape speak first. If Heatmap will not fit a banner, keep the number and show the chart on the landing page.
Check each criteria to confirm findings against the atlas verdict.
