This scatter plot visualizes car data from the UCI Machine Learning Repository’s Auto MPG dataset, plotting horsepower against vehicle weight. The code uses D3 v5 with `scalePoint` and `scaleLinear` for axis mapping, and `axisLeft`/`axisBottom` for gridlines. Circles are rendered as SVG elements with red, semi-transparent fill. The chart includes margin-based layout, axis labels, and a title, with styling applied via external CSS.
