This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for various car brands. The x-axis represents horsepower, the y-axis represents torque, and the bubble size encodes highway MPG, with color distinguishing each brand. Built with D3 v7, the SVG visualization includes interactive tooltips that appear on mouseover, showing the car make. A legend explains the bubble size scaling for highway MPG values. The chart uses ordinal color scaling via `d3.interpolateTurbo` and linear scales for positioning and sizing, with data loaded from a CSV file.
