This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes horsepower (x-axis) and torque (y-axis), while radius maps to highway MPG and color distinguishes vehicle brands. The visualization uses d3.csv to load data, d3.scaleLinear for axes and sizing, d3.scaleOrdinal with d3.interpolateTurbo for color assignment, and includes interactive tooltips on mouseover. Static SVG rendering with an animated hover effect highlights individual data points, with legends for both MPG and make categories.
