This scatter plot displays the relationship between horsepower and weight for a sample of cars from the auto-mpg dataset. Each red circle represents one car, with its position determined by D3's `scaleLinear` mapping the horsepower and weight values to screen coordinates. The visualization uses D3 v5's `csv` to load remote data, `axisLeft` and `axisBottom` for the labeled axes with grid lines, and SVG circles with opacity for the points. The plot is rendered entirely in SVG within a fixed 960x500 viewport.
