This interactive dashboard visualizes football player performance across European leagues, showing how metrics like goals, shots, and expected goals vary by league and season. It integrates a scatter plot, bar chart, line chart, and parallel coordinates plot, all driven by React state management. Users can filter data through dropdown menus, brush the parallel coordinates to filter players, and hover over marks for details. The visualization leverages D3’s `scaleLinear`, `scalePoint`, `brushY`, and `transition` APIs, rendering animated updates from a Kaggle dataset of top league scorers.
