Free Map Chart Maker

A map chart (often called a choropleth) shades geographic regions with color to encode a numerical value. The shape is the map; the color is the data. The viewer immediately sees which regions are high and which are low, without reading a table.

Map charts are especially powerful for business, health, and policy contexts where geography carries real meaning. Sales per country, disease incidence per state, election results per district — the geographic pattern often carries the story.

Our map chart maker runs in the browser against a built-in world map. You enter a value per country (using ISO country codes), choose a color scale, and export. No GIS software, no boundary files to manage.

Use a map chart when geography is the story. If the insight is "X country outperforms Y", a bar chart is usually clearer. But if the insight is "there is a regional pattern — Europe is high, Asia is mixed, Africa is low" — the map shows the pattern at a glance where a bar chart would just list values.

A common mistake is using a map when a bar chart would work better. If you are comparing a handful of countries without regional clustering, the bars win. If the audience will want to trace a regional pattern, the map wins.

Another common use: highlighting coverage gaps. Show the countries you have data from in a saturated color and the gaps in a neutral color — the map is now a progress report on data collection.

Pick the right color scale. Sequential (single-hue light-to-dark) for magnitude. Diverging (two hues with a neutral midpoint) when the data has a meaningful baseline, like above or below average. Categorical for discrete buckets, like political parties.

Limit color categories to five or six. More than that, the map becomes a mosaic no one can decode without constantly checking the legend.

Use muted color for unsurveyed or missing-data countries. A light gray reads as "no data" without drawing the eye away from the colored regions.

Label only the most important regions on the map itself. A legend is usually enough for the rest. Too many labels produce visual noise.

Our map infographic maker is a close cousin designed for editorial and travel content — showing project locations, destinations, or pins on a map. The map chart maker on this page is about shading regions by value, not pinning locations.

Use the infographic map when the story is "here are specific places". Use the map chart when the story is "here are regional values compared".

Both tools use the same underlying map widget in the full editor, so you can combine pins and shaded regions on the same map for a hybrid view.
