This scatter plot visualizes the relationship between horsepower and highway MPG for cars in a bubblechart dataset, with each point colored by car make. The visualization uses D3 v6 to load CSV data from a GitHub repository, then renders SVG circles scaled via `scaleLinear` for both axes. Axes are generated with `axisLeft` and `axisBottom`, while colors are assigned using `scaleOrdinal` with `schemeTableau10`. A legend is appended to distinguish makes, and all elements are drawn directly to the SVG canvas.
