This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble’s position maps horsepower (x-axis) and torque (y-axis), while its size encodes highway MPG. Color distinguishes car brands, with a legend explaining the size scale and a color key. Built with D3 v7, the SVG visualization includes animated tooltips on hover, showing the car make. Data comes from a local CSV file, and the chart uses D3’s scaleLinear, scaleOrdinal, and interpolateTurbo APIs for scaling and coloring.
