This bubble chart visualizes the correlation between average torque, horsepower, and highway MPG for various car makes. Each circle’s position maps torque and horsepower, while its size encodes highway MPG and its color represents the car make. The visualization includes interactive tooltips that display the make on hover, a color legend, and a size legend for MPG values. Built with d3.v7, it uses scaleLinear for axes and bubble sizing, scaleOrdinal with interpolateTurbo for colors, and SVG rendering with mouse event handlers.
