This interactive bubble chart shows the correlation between average horsepower, torque, and highway MPG for 31 car models, with bubble size encoding MPG and color distinguishing each make. Built with D3 v7, it renders SVG circles with smooth hover interactions and tooltips displaying model names. The visualization includes dual legends for bubble size (highway MPG) and color-coded makes, using d3.scaleOrdinal with interpolateTurbo colors and d3.scaleLinear for both axes and bubble radius.
