This scatter plot shows the relationship between car horsepower and weight, using red semi-transparent circles. The visualization is built with D3 v5, using `scaleLinear` for both axes, `axisLeft` and `axisBottom` for gridlines, and SVG rendering. Data comes from the Plotly auto-mpg dataset, loaded via `cv`. The chart also demonstrates custom axis styling, including tick lines, rotated axis labels, and a title, all styled with CSS classes.
