This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble’s position maps horsepower and torque on the x- and y-axes, while its size and color encode highway MPG and manufacturer. Tooltips display the vehicle make on hover. Built with d3.csv and SVG, it uses d3.axisBottom, d3.axisLeft, d3.scaleLinear, and d3.scaleOrdinal, with d3.interpolateTurbo for coloring, and includes a legend for bubble size and make categories.
