This example shows a reusable scatter plot that compares Quidditch player performance, plotting total points against average points per match. Data is loaded from a gist and aggregated by player before rendering with D3 v6. The visualization uses d3.scaleOrdinal for house colors and symbols, d3.symbolGenerator for point shapes, and d3.axisBottom/Left for axes. Hovering highlights individual points and logs player details to the console, while a legend identifies the four houses.
