This scatter plot displays the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG dataset. Each circle represents a car, with red semi-transparent points revealing overlapping data density. The visualization uses D3 v5’s `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs to load and parse the data, scale the axes, and render the SVG. Grid lines extend from the ticks, and labeled axes with a title clarify the plotted variables.
