This scatter plot visualizes the relationship between horsepower and weight for 398 cars from the UCI Machine Learning Repository’s Auto MPG dataset. Red semi-transparent circles mark each vehicle, with axis labels and a title displayed alongside tick marks. Built with D3 v5, it uses `csv` to load data, `scaleLinear` for both axes, and `axisBottom` and `axisLeft` to render the coordinate system. The SVG-based chart applies a margin convention and uses CSS to style circles, ticks, and text.
