This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble’s position is determined by horsepower on the x-axis and torque on the y-axis, while its size encodes highway MPG. The color of each bubble represents the car make. Built with D3.js v7, the visualization uses SVG for rendering and includes interactive tooltips that display the car make upon mouseover, as well as legends for both bubble size and color categories. Data is loaded from a CSV file.
