Cars Scatterplot
This scatterplot displays the relationship between horsepower and weight for a dataset of cars, with each car represented as a semi-transparent red circle. The visualization uses D3 v5 and renders as SVG, employing `d3.scaleLinear` for both axes with the data loaded via `d3.csv` from a remote URL. Gridlines are drawn through axis tick marks, and axis labels and a title are added as SVG text elements.
