This bubble chart displays the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble represents a make, with its x-position mapped to horsepower, y-position to torque, and bubble size scaled by highway MPG. The visualization uses an SVG renderer with D3 v7, employing `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for color mapping, and interactive tooltips. A legend encodes both bubble size and car make, while data comes from `bubblechart.csv`.
