This visualization shows the relationship between horsepower and weight for cars from the UCI Machine Learning Repository Auto MPG dataset. The scatter plot encodes horsepower on the x-axis and weight on the y-axis, with semi-transparent red circles representing individual vehicles. Built with D3 v5, the code uses `csv` to load the data, `scaleLinear` for both axes, and `axisBottom` and `axisLeft` to render the tick marks and labels. The SVG output includes a title and axis labels formatted with custom CSS styling.
