This scatter plot visualizes the relationship between horsepower and miles per gallon for car models, with each circle representing a vehicle. The axes are labeled and the chart includes a title. The visualization uses d3.scaleLinear to map data values to screen coordinates, d3.axisBottom and d3.axisLeft for tick marks, and SVG circles with steelblue fill and opacity. Data is loaded asynchronously from a CSV file using d3.csv.
