This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for various car makes. Each circle is positioned by its horsepower and torque on the x and y axes, with its size encoding highway MPG and color distinguishing the car brand. Built with D3 v7, the SVG chart uses linear scales, a color legend, and interactive tooltips that appear on hover. The data comes from a CSV file, and the visualization is rendered as an animated SVG.
