This scatter plot displays the relationship between horsepower and weight for a dataset of cars, with each circle representing a vehicle. The visualization uses D3 v5 to render an SVG, employing `scaleLinear` for both axes and `axisBottom`/`axisLeft` to generate tick marks and grid lines. Data from the auto-mpg.csv file is loaded via `csv`, and circles are appended with a fixed radius of 18 pixels, styled red with partial opacity. Axis labels and a title are positioned manually within the chart's margins.
