This bubble chart visualizes the relationship between average horsepower (x-axis), torque (y-axis), and highway MPG (bubble size and legend) for various car makes. Built with D3 v7, it renders an SVG with animated transitions, using a turbo color scale to differentiate car brands. Interactive tooltips display the make of each vehicle on mouseover, while a legend shows both MPG value scaling and color-coded brand categories, with data loaded from a CSV file.
