This interactive scatter plot visualizes the relationship between car mileage (MPG) and price, with each point colored by car color. The chart uses D3 v7 and loads data from a GitHub Gist, presenting an SVG rendered via a viewBox for responsiveness. Users can hover over points to see details. The visualization employs d3.scaleLinear for axes, d3.scaleOrdinal for categorical colors from ColorBrewer, and d3.csv for data loading, with a d3-legend for the color key.
