This scatter plot shows the correlation between average horsepower (x-axis), torque (y-axis), and highway MPG for 31 car makes, with bubble size encoding fuel efficiency and color distinguishing each brand using `d3.scaleOrdinal` with `d3.interpolateTurbo`. The D3 v7 SVG visualization includes hover tooltips, a size legend for MPG values, and a color legend listing all makes. Data comes from the BUBBLECHART.csv file, rendered with React and animated opacity changes on mouse interactions.
