This interactive bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for various car makes. Using d3.v7, the chart maps torque to the y-axis, horsepower to the x-axis, and highway MPG to the bubble size and color via a linear scale and ordinal color scale. Built with SVG and animation, it reads from a CSV file, adds axis labels and a legend for MPG values, and includes a tooltip that displays the car make on mouseover.
