This interactive map visualizes 2024 automobile metrics, allowing comparison of Total Vehicles and EV Sales across major countries. Country colors reflect the selected metric, while circle sizes encode EV sales volume. Built with D3.js v7, the visualization projects country boundaries from a world-atlas TopoJSON file using `d3.geoPath` and integrates a hover tooltip. A separate legend and toggling buttons drive the color-encoding switches, with the page styled via a clean card-based CSS layout.
