This choropleth map visualizes internet users per 100 people across countries using 2021 data, with color intensity representing usage rates from a green scale. The map includes hover tooltips showing exact percentages and supports zooming via `d3.zoom` with adjustable stroke widths. Built with D3 v7 and TopoJSON, it renders countries using `d3.geoNaturalEarth1` projection and `d3.geoPath`, with a custom color legend and graticule overlay.
