This world map visualizes internet users per 100 people in 2015, using a red sequential color scale to indicate adoption rates, from light shades for low usage to dark red for high usage. Hovering over a country reveals a tooltip with its exact percentage, and users can zoom and pan the map via d3.zoom. The visualization is built with D3 v7, using d3.geoNaturalEarth1, d3.geoPath, and d3.geoGraticule to render the geographic features from TopoJSON data sourced from the visionscarto-world-atlas.
