This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position encodes horsepower and torque on the x- and y-axes, while its radius and color represent highway MPG and manufacturer, respectively. The chart uses d3.csv to load the dataset, d3.scaleLinear for axes and bubble sizing, and d3.scaleOrdinal with interpolateTurbo for color mapping. Interactive tooltips appear on mouseover, and legends for MPG and car makes are rendered alongside the SVG animation.
