This bubble chart visualizes the correlation between a vehicle's average horsepower, torque, and highway MPG for various car makes. It maps horsepower to the x-axis, torque to the y-axis, and uses bubble size to represent highway MPG, with color differentiating brands. Built with D3 v7, the visualization renders as an SVG and features an interactive tooltip that appears on mouseover, showing the vehicle make. It also includes legends for bubble size and color categories, with data read from a local CSV file.
