This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle's position is determined by its horsepower (x-axis) and torque (y-axis), while the bubble size scales with highway MPG. The chart uses D3.js v7 to render SVG graphics, with color encoding categorical car makes and a custom tooltip providing specific details on hover. It includes legends for bubble size and color, and animates user interactions smoothly.
