An interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble's position encodes horsepower and torque, while its size maps to highway MPG and its color distinguishes different manufacturers. Built with d3.v7, the SVG visualization uses linear scales and includes interactive tooltips on mouseover. A legend displays both the bubble size scale and color-coded car makes. The data is loaded from a CSV file.
