Make a tile grid map with your data

Use a tile grid map when…

  • When equal representation matters (elections)
  • When geography would mislead
  • Comparing per-region rates where small regions matter as much as large ones

Avoid when…

  • When geographic position is important
  • Non-standard region sets

Guiding principles

Consider instead

Common mistakes

  • Unlabeled tiles

  • Poor color scale

History

Evolved from hex grid maps; popularized by Bloomberg and The Guardian in the 2010s.

Accessibility notes

Label each tile and pick a colorblind-safe palette (ColorBrewer YlOrRd or viridis for sequential; RdBu for diverging) — the chart leans heavily on color-luminance. Provide a sorted data table as fallback.
