This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes, using the x-axis for horsepower, y-axis for torque, and bubble size for MPG. Each car make is individually colored, and the chart includes a legend showing both the MPG scale and make colors. Built with D3.js version 7, the visualization uses `d3.csv` to load data, `d3.scaleLinear` for axes and bubble sizes, and `d3.interpolateTurbo` for color mapping, with interactive tooltips appearing on mouseover. All elements are rendered as SVG, and the chart animates in when the data loads.
