This visualization shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble is positioned by horsepower on the x-axis and torque on the y-axis, while its radius and color encode highway MPG using d3.scaleLinear and d3.scaleOrdinal with d3.interpolateTurbo. A tooltip displays the car make on hover. The chart is rendered with SVG in D3 v7, reading data from a CSV file, and includes a legend for MPG and car makes.
