This scatter plot visualizes the relationship between car weight and horsepower using data from the UCI Machine Learning Repository’s Auto MPG dataset. Red, semi-transparent circles represent individual cars, with weight on the x-axis and horsepower on the y-axis. The visualization uses D3 v6 with d3.csv, d3.scaleLinear, d3.extent, axisBottom, and axisLeft to render axes and grid lines in SVG. The chart includes labeled axes, a title, and uses a margin-based layout with tick marks extending across the plotting area.
