This network graph visualizes country-level internet speed classifications as colored nodes—green for High, orange for Medium, and red for Low—with links connecting every possible pair. Built with d3.forceSimulation, d3.forceLink, d3.forceManyBody, and d3.forceCenter, it loads CSV data via d3.csv and renders nodes as SVG circles, supporting drag interactions. Node positions update continuously through the simulation’s tick event, with each node labeled by its country name via a tooltip title element.
