This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. The x-axis maps horsepower, the y-axis maps torque, while the size of each bubble encodes highway MPG and the color distinguishes different car manufacturers. A legend showing the MPG scale is on the right, and color-coded dots identify each make. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble size, and `d3.interpolateTurbo` to assign a color to each make. The SVG render includes an interactive tooltip that appears on mouseover, displaying the car make. Data is loaded from a local CSV file.
