This bubble chart displays average horsepower, torque, and highway MPG for various car brands, with each bubble’s position on the x- and y-axes representing horsepower and torque, and its size encoding highway MPG. The color of each bubble corresponds to the car make, and hovering reveals a tooltip with the brand name. Built with d3.v7 and SVG, it includes axes, a size legend, and a color legend, reading data from a CSV file.
