This visualization displays the correlation between horsepower, torque, and highway MPG for different vehicle makes, using a bubble chart where the x-axis shows average horsepower, the y-axis shows average torque, and bubble size represents highway MPG. Each car make is colored using a distinct color from the `d3.interpolateTurbo` scale, and hovering over a bubble reveals the make via a tooltip. The chart includes a legend for the MPG bubble sizes and a color-coded key for the makes. It is built with D3.js v7, reading data from a CSV file and rendering as an SVG with interactive animations.
