This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across different car makes. Each circle represents a car make, with its x-axis position indicating horsepower, y-axis position indicating torque, and radius representing highway MPG. Color encodes the car make, and hover interactions reveal the make name via a tooltip. Built with D3 v7 and React, the chart uses `scaleLinear` for axes and bubble size, `scaleOrdinal` with `interpolateTurbo` for color mapping, and SVG for rendering with animation.
