This scatterplot visualization shows the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each bubble represents a car brand, with its x-position indicating horsepower, y-position indicating torque, and bubble size scaled to highway MPG. The chart includes a color-coded legend for car makes and an interactive tooltip displaying the make on hover. Using D3 v7's `d3.scaleLinear` and `d3.scaleOrdinal` with `d3.interpolateTurbo`, the visualization renders as SVG with smooth hover transitions and mouse event handlers for tooltip positioning.
