A scatter plot displays the relationship between horsepower and weight for cars from the auto-mpg dataset, using red semi-transparent circles to reveal overlapping points. The visualization is rendered as SVG within a React application, leveraging D3 v5’s `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` to construct the axes and scales. Grid lines extend across the plot, and axis labels and a title are manually appended to the SVG group elements, with data loaded asynchronously via `csv`.
