This world map displays internet usage as a proportion of each country’s population for 2021, with countries colored on a sequential scale from low to high usage. Users can hover over any country to see its exact value in a tooltip and zoom or pan the map using d3.zoom. The visualization builds its geographic paths with d3.geoPath and topojson-client, loads data from the internet_users.csv file, and renders a legend using d3.scaleOrdinal and a custom colorLegend function.
