This scatter plot from the UCI Machine Learning Repository's Auto MPG data set visualizes the relationship between horsepower and weight for cars. Red semi-transparent circles, rendered as SVG elements, show a positive correlation where heavier cars generally have more horsepower. The visualization uses D3 v5 functions including `scaleLinear` for axis scaling, `axisLeft` and `axisBottom` for coordinate axes, and `csv` for data loading, with custom styles applied via CSS.
