This bubble chart displays the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle represents a make, positioned by its horsepower (x-axis) and torque (y-axis), with radius encoding highway MPG and color distinguishing brands, using D3.js with linear scales. Hovering reveals a tooltip via mouseover events, while the legend explains the MPG bubble sizes and color-coded makes. The visualization reads from a CSV, uses SVG rendering, and applies the `d3.interpolateTurbo` color scheme.
