This interactive bubble chart visualizes the correlation between average torque, horsepower, and highway MPG for various car makes. Each circle’s position encodes horsepower and torque, while its radius and color represent highway MPG and the vehicle brand, respectively. Hovering over a bubble reveals the car make via a tooltip. Built with D3.js v7, the visualization uses SVG, linear scales, and an ordinal color scale, with a legend displaying MPG values and brand colors. Data is loaded from a CSV file.
