This bubble chart shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle represents a car brand, positioned by its horsepower (x-axis) and torque (y-axis), with the circle’s radius encoding highway MPG and its color distinguishing the manufacturer. The visualization is built with D3 v7, using `d3.scaleLinear` for axes and bubble size, a tooltip on mouseover, and SVG animation for interactivity. It includes a legend for both MPG values and color-coded makes.
