This scatter plot visualizes the relationship between horsepower and weight for a dataset of cars, with each red point representing an individual vehicle. The visualization loads CSV data from a remote URL and converts numeric fields before rendering. Using D3 v5, the chart employs `scaleLinear` for both axes, `axisBottom` and `axisLeft` for tick marks, and SVG circles with opacity to show data density. Axis labels and a title are added via SVG text elements, with gridlines generated through tick size adjustments.
