Internet penetration by country

Percentage of the population online, drawn as a single-hue sequential choropleth. One hue with varying lightness is the correct choice when the data has a natural zero, because readers can rank areas without consulting the legend.

Loading CSV data
Natural Earth 5.1.2 boundaries; World Bank 2023 indicator snapshot joined by ISO3. Missing observations remain grey. GDP is in thousands of current US dollars; internet use is a percentage.

What to look at

  • Single-hue ramp: lightness carries the magnitude, so ranking does not require the legend.
  • The tinted basemap keeps land visible underneath so small countries stay findable.
  • World Bank indicator values are joined by ISO3 country codes to avoid name mismatches.

Source columns

These fields describe the example data. CSV and Excel use first-row headers; GIS formats store geometry and feature properties. Required geometry depends on the map type.

Rebuild it with your own data

  1. 1

    Get your CSV file ready

    The example fields are country, internet_percent. For CSV or Excel, put headers in the first row. GIS files carry geometry and feature properties. Prepare any grid, catchment or route geometry before import.

  2. 2

    Drop it into the studio

    MapCrafter detects the geometry, counts the features, and shows the layers it found.

  3. 3

    Style the imported layer

    Pick which column drives colour, and which drives size or width where relevant.

  4. 4

    Pick a basemap theme

    Mint is used here. 15 other basemaps are available, including official OpenFreeMap styles. Switch using Layers & basemap.

  5. 5

    Share or export

    Publish a link, embed the map, or export a PNG at print resolution.

Questions about this example

What file format does this choropleth use?
This example illustrates CSV data. The live preview uses GeoJSON geometry. MapCrafter reads CSV directly, along with Excel, CSV, KML, KMZ, GPX, GeoJSON, TopoJSON and zipped Shapefile. No conversion step and no desktop software.
What columns does the source data need?
The file used here has 2 columns: country, internet_percent. For tabular imports, supply coordinate columns, WKT or GeoJSON geometry, or address columns for an explicit geocoding step. Polygon and line files carry their geometry separately from these attributes.
Can I use my own data with this map type?
Yes. Open the studio, drop in your file, and MapCrafter detects the geometry and applies a starting style. Then style the layer and choose which property drives colour, size or width. The studio can render a point heatmap, but grids, routes and catchment polygons must be prepared before import.
Can I export or share the finished map?
Each map can be published to a short share link, embedded in another page with an iframe, or exported as a print-resolution PNG. The cleaned-up geometry can also be exported as GeoJSON. All of that is available on the free tier.
Where does the data in this example come from?
Natural Earth 5.1.2 boundaries; World Bank 2023 indicator snapshot joined by ISO3. Missing observations remain grey. GDP is in thousands of current US dollars; internet use is a percentage.
