This example visualizes the distribution of wine quality ratings from the WineQT dataset, showing the count of wines for each quality score as a pie chart. The SVG chart is generated with D3 v6, using `csv` to load data from a GitHub repository, `pie` and `arc` to compute and draw slices, and `scaleOrdinal` with `schemeCategory10` for colors. A custom legend displays each quality label with its count.
