This animated D3.js bubble chart explores the correlation between average horsepower, torque, and highway MPG for various car makes, using data from a GitHub-hosted CSV file. SVG circles are positioned by horsepower on the x-axis and torque on the y-axis, with radius encoding highway MPG and color distinguishing makes via a d3.scaleOrdinal with interpolateTurbo. Interactive tooltips appear on mouseover, while custom legends for bubble size and car makes clarify the encodings.
