This interactive scatter plot displays the relationship between car mileage and price, with individual dots colored by fuel type. Built with D3.js (v7), it renders as an SVG chart with axes, labels, and a hover tooltip that reveals the car name, fuel, mileage, and price. The visualization loads a CSV dataset from a GitHub gist, uses `d3.scaleOrdinal` for color mapping, and applies CSS transitions to highlight dots on hover.
