This interactive world map visualizes automobile metrics for 2024, showing both total vehicles and EV sales by country. Toggle buttons switch the choropleth color scale between these two metrics, while circle size represents EV sales volume and circle color encodes average car price. The visualization uses D3 v7 with d3.geoPath and topojson-client to render world topography, with SVG elements providing animated transitions when switching between metrics. A legend dynamically updates to reflect the current color scale, and tooltips provide detailed country-level data on hover.
