This world map visualizes global internet usage percentages across countries, with a purple sequential color scale indicating usage rates from 0-30% to 91-100%, and hover interactions revealing exact country names and usage values via a tooltip. Data from a CSV file is joined to TopoJSON country geometries loaded from world-atlas, projected using `d3.geoNaturalEarth1()` and rendered with `d3.geoPath()`. The map uses D3's `scaleThreshold` for color binning, with a custom legend and styled SVG paths for the choropleth display.
