This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car manufacturers. Each car brand is represented by a colored bubble, with its position determined by horsepower (x-axis) and torque (y-axis), while the bubble’s size corresponds to its highway MPG value. The visualization uses D3.js v7 with SVG rendering and includes interactive tooltips that display the manufacturer name on hover. A legend on the right uses scaled circles to indicate MPG values, and a color-coded scheme distinguishes each brand. The data is loaded from a CSV file.
