This interactive bubble chart visualizes the relationship between average horsepower, torque, and highway MPG across 31 car makes, with bubble size encoding MPG and color distinguishing manufacturers. Built with D3 v7, the SVG chart includes a tooltip displaying the make on hover, along with legends for bubble size and color categories. The x-axis represents horsepower, the y-axis torque, and the data is loaded from a CSV file using `d3.csv`.
