This example shows a pie chart whose five slices are filled with distinct geometric textures instead of solid colors. Each slice uses a different pattern generated with the `textures` library, including hexagons, crosses, caps, woven, and waves. The chart is built using `d3.pie` and `d3.arc` to compute the slice paths, while `d3.scaleOrdinal` maps each data category to a texture URL. Rendered as an SVG, the chart includes a black stroke around each slice to visually separate the textured areas.
