This scatter plot displays the relationship between horsepower and weight for cars, using red semi-transparent circles scaled along linear axes. The visualization loads data from a remote CSV file and renders it as an SVG, with D3’s `scaleLinear`, `axisBottom`, and `axisLeft` APIs generating gridlines and tick marks. Axis labels and a title clarify the chart, while margins and redundant axis titles structure the layout. The code imports specific functions from D3 v5 and applies CSS styling for opacity and typography.
