This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Circles are positioned by horsepower (x-axis) and torque (y-axis), with their radius and color encoding highway MPG using a linear scale and a turbo-interpolated ordinal color scale, respectively. Built with D3 v7, the SVG graphic includes interactive tooltips on hover and a legend for bubble sizes. Data is sourced from a local CSV file.
