This scatter plot visualizes the relationship between fuel efficiency (MPG) and horsepower for a dataset of automobiles, with each car represented as a semi-transparent circle. The visualization uses D3 v5's linear scales (`scaleLinear`) to map data values to coordinates, and axes are rendered with `axisLeft` and `axisBottom`, including grid lines and custom tick formatting. The SVG canvas is populated by appending circle elements, and the data is loaded asynchronously from a CSV file using the `csv` function.
