This scatterplot visualizes the relationship between horsepower and weight for a dataset of cars, with each point representing an individual vehicle. The chart uses D3 v5 to load data from a CSV file via the `csv` method and render SVG circles. Axes are created with `axisBottom` and `axisLeft`, while `scaleLinear` maps the data domain to pixel coordinates, with grid lines added through customized tick sizes. The visualization includes labeled axes and a title, with circles styled in semi-transparent steelblue.
