This bubble chart shows the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes horsepower and torque, while its radius represents highway MPG, and color distinguishes manufacturers. Hovering reveals the car make via a tooltip. The visualization uses d3.csv to load data, d3.scaleLinear for axes and sizing, d3.scaleOrdinal with interpolateTurbo for coloring, and SVG circles with mouse event handlers for interaction. A legend displays MPG values and make colors.
