This scatter plot displays the relationship between car weight and horsepower using data from the auto-mpg dataset. Each semi-transparent steelblue circle represents a car, plotted by D3.js v5 with `scaleLinear` axes and axis labels. The code uses `csv` loading, `extent` for domains, and `axisBottom`/`axisLeft` to render gridlines and ticks. The SVG rendering includes a title and rotated y-axis label, with margins defining the inner plotting area.
