This scatter plot visualizes the relationship between MLB run differentials and winning percentages for teams from 2010 to 2022. It uses color-coded circles to represent different league divisions (NL West, AL East, etc.), with each point positioned by its run differential (x-axis) and win percentage (y-axis). The visualization is built with D3 v6, loading CSV data from a GitHub repository and rendering SVG circles. The code uses D3's scaleLinear, extent, axisLeft, and axisBottom APIs alongside custom color-mapping logic to distinguish league divisions.
