A scatter plot of automobile data from the UCI Machine Learning Repository's Auto MPG dataset, this visualization maps engine horsepower on the x-axis against vehicle weight on the y-axis using red, semi-transparent circles. The chart renders as an SVG and employs D3 v5's `scaleLinear` for axis scaling, `axisLeft` and `axisBottom` for tick marks, and `extent` for domain calculation. Data is loaded as CSV and parsed into numeric values before being plotted.
