This bubble chart shows the correlation between average horsepower, torque, and highway MPG across different car makes. Each bubble’s position encodes horsepower and torque, its radius encodes highway MPG, and its color distinguishes car makes. Built with D3 v7, the visualization uses SVG circles with interactive tooltips that display the make on hover. A legend maps both bubble size to MPG values and color to the categorical make variable, with data sourced from a CSV file.
