This bubble chart shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s horizontal position encodes horsepower, its vertical position torque, and its size reflects highway MPG, while color distinguishes the manufacturer. The visualization uses D3.js v7 with SVG rendering and interactive tooltips that display the car make on hover. Animated transitions are applied to the tooltip’s opacity. The chart includes a legend for bubble size values (20 and 40 MPG) and a color-coded list of makes, all positioned with fixed coordinates. Data comes from a local CSV file.
