{"version":"1.0","type":"rich","title":"loading the data for visualization","description":"This example shows a donut chart of all CSS named colors, with each slice filled by its corresponding color value from a CSV dataset. The visualization loads data asynchronously using D3’s `csv` method and stores it in React state via the `useState` and `useEffect` hooks. Each data row is rendered as an SVG path using `d3.arc`, positioned around a central point. While loading, the app displays a simple “loading…” message before rendering the complete chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4bbd9813b171428fbc8711db3d8f448a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
