This bubble chart shows the correlation between average horsepower, torque, and highway MPG across 31 car makes, with each bubble’s position encoding horsepower and torque, while its radius and color represent highway MPG and car make, respectively. A tooltip displays the car make on hover, and a legend explains the bubble size scale for highway MPG values. The visualization is built with D3 v7, using `d3.csv` for data loading, `d3.scaleLinear` for axes and size, `d3.scaleOrdinal` with `d3.interpolateTurbo` for color, and SVG elements for rendering.
