This gallery example visualizes a subset of the classic “car.csv” automobile dataset, plotting fuel economy against model year. Each car is drawn as a small circle, positioned by its year and economy values, with the point’s color encoding the car’s brand. The implementation uses the D3.js library, specifically `d3.forceSimulation` to arrange overlapping labels or points and `d3.geoPath` for any map projection, though the core scatter plot is rendered via standard SVG circles. The visualization is built entirely from client-side JavaScript, directly parsing the CSV file to drive the animated layout.
