This scatter plot displays the relationship between horsepower and weight for various car models from the UCI Machine Learning Repository’s Auto MPG data set. Each red, semi-transparent circle represents one vehicle, with its horizontal position mapped to horsepower and vertical position to weight. The visualization uses D3 v5’s `scaleLinear`, `axisBottom`, and `axisLeft` APIs to construct the axes, while CSV data is loaded via D3’s `csv` function. The chart is rendered as an SVG with custom styling for ticks, labels, and the title.
