This visualization displays political donation amounts across major sports leagues (NBA, NFL, MLB, NHL, WNBA, NASCAR), with a multi-line chart grouping donations by party affiliation. Using D3 v6 with SVG rendering, the code loads data from a CSV file, applies time and linear scales, and uses `d3.group` to nest entries by party before drawing line paths with `d3.line`. Axes are generated with `d3.axisBottom` and `d3.axisLeft`.
