This visualization shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble’s position encodes horsepower and torque on the x and y axes, while its size represents highway MPG and its color distinguishes the car manufacturer. Hovering reveals the make via a tooltip. The chart uses D3 v7 with SVG and animation, employing d3.scaleLinear, d3.scaleOrdinal, d3.interpolateTurbo, and d3.csv to load and render the bubblechart.csv data, includes a legend for MPG and color-coded car makes.
