{"version":"1.0","type":"rich","title":"textured pie chart","description":"This example shows a textured pie chart that visualizes data from a CSV file containing postal codes. The chart uses D3.js version 4 to compute the pie layout with `d3.pie()` and render each slice as an SVG path via `d3.arc()`. Distinct geometric patterns—hexagons, crosses, caps, woven, and waves—are applied to the slices using the Textures library’s `textures.paths()` API, combined with a custom color scale. The data is fetched asynchronously from `postalCodes.csv` using the Fetch API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eeb79737d01e446e914a8a05690d7b13?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
