This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position encodes horsepower (x-axis) and torque (y-axis), while its size represents highway MPG and its color distinguishes the car manufacturer. The visualization includes interactive tooltips that display the make on hover, along with legends for both bubble size and color categories. Built with d3.v7, it uses d3.scaleLinear for axes and bubble sizing, d3.scaleOrdinal with d3.interpolateTurbo for colors, and SVG rendering with animated hover effects.
