This bubble chart displays the correlation between average horsepower, torque, and highway MPG across various car makes, with each circle's position on the x- and y-axes representing horsepower and torque, respectively, and its radius scaling with highway MPG. The chart uses D3.js v7 to load CSV data, render the SVG, and apply linear scales for axes and bubble size, along with an ordinal color scale assigned per make. Interactive tooltips appear on mouseover, and a legend encodes the MPG scale and color categories.
