This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes, with each bubble's position on the x- and y-axes representing horsepower and torque, and its size and color encoding MPG and car make, respectively. Rendered as an SVG using D3 v7, the visualization includes interactive tooltips on hover and legends for bubble size and categorical colors, with the dataset loaded from a CSV file.
