This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG across car makes, with each bubble’s position on the x-axis representing horsepower, the y-axis representing torque, and the bubble size encoding highway MPG. Color distinguishes different manufacturers. The chart uses D3 v7’s scaleLinear for axes, scaleOrdinal for color assignment, and scaleLinear for bubble size. Interactions include tooltips on hover, implemented via D3’s select and style methods. Data is loaded from a CSV file using d3.csv.
