This interactive bubble chart visualizes correlations between average horsepower, torque, and highway MPG across 31 car makes from a CSV dataset. Each bubble’s x-position maps to horsepower, y-position to torque, and radius to highway MPG, with color encoding make identity. Built with d3.v7, the SVG chart features a linear radius scale, ordinal Turbo color scale, and hover tooltips displaying the car make. The visualization includes two legends: one for bubble size representing MPG values and another color-coded legend listing all makes. Interactive mouseover events trigger tooltip transitions showing contextual data.
