This scatter plot visualizes the relationship between vehicle weight and horsepower using the auto-mpg dataset loaded via d3.csv. The visualization employs d3.scaleLinear for both axes, with the x-axis representing weight and the y-axis horsepower. SVG circles with a fixed radius mark each data point, rendered in steelblue with 50% opacity. The chart includes labeled axes, grid lines created through axis tick sizing, and a title, all styled through the provided CSS.
