This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for various car brands. Each circle's position encodes horsepower and torque, while its radius and color represent highway MPG, with a legend for scale. The visualization uses D3.js v7, reading data from a CSV file. It implements interactive tooltips on mouseover and employs D3's scaleLinear, scaleOrdinal, and interpolateTurbo for encoding, rendering via SVG.
