This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes, using a CSV dataset. Each circle’s position encodes horsepower and torque on the x- and y-axes, while its size and color represent highway MPG and make, respectively. Built with d3.v7, it renders as an SVG with interactive tooltips on hover and a legend for both bubble size and color. The color scale uses d3.interpolateTurbo and a scaleOrdinal for categorical distinction.
