This scatter plot visualizes the relationship between horsepower and weight for a dataset of cars, with each point representing a vehicle. The visualization uses D3 v5’s `scaleLinear`, `axisBottom`, and `axisLeft` to map the quantitative values and render labeled axes with grid lines. Circle elements are drawn in SVG with a red, semi-transparent fill to show data density. The data is loaded from a CSV file via `d3.csv` and values are parsed as numbers before being scaled and plotted.
