This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes, sourced from a CSV file. Each circle's position is determined by its horsepower (x-axis) and torque (y-axis), while its size reflects highway MPG and its color encodes the car make. Built with d3.v7, the SVG rendering includes interactive tooltips on mouseover, a legend for MPG values, and a color-coded make legend.
