This bubble chart visualizes the correlation between average horsepower (x-axis), torque (y-axis), and highway MPG (bubble size and color) for various car makes. The chart uses a linear scale for both axes, with bubble size representing highway MPG and color encoding the car manufacturer. Built with D3.js v7, it renders as an SVG with animated transitions. The visualization includes interactive tooltips that display the car make on hover, along with legends for both bubble size and color categories. The data is loaded from a local CSV file.
