This scatter plot displays the relationship between horsepower and weight for cars from the UCI Auto MPG data set, with each red semi-transparent circle representing a single vehicle. The visualization uses d3.csv to load the data, d3.scaleLinear for both axes, and d3.axisBottom and d3.axisLeft to render the tick marks and labels. The SVG output includes axis labels and a title, with circles positioned via the x and y scales and styled through CSS opacity.
