{"version":"1.0","type":"rich","title":"Fork of D3 and React Hooks","description":"A React hook-based pie chart example demonstrates how to render D3-generated SVG arcs with state-managed data updates. Using `useState` and `useEffect`, the app generates random numeric data with `d3.range` and `Math.random`, then passes it to a `PieSvg` component that computes arc paths via `d3.pie()` and `d3.arc()`. A button click triggers `setData` to regenerate values, while a separate `ColorLegend` component renders interactive colored circles with hover effects that fade non-hovered ticks using opacity. The visualization shows D3-created SVG elements managed entirely by React’s render cycle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fd16110c83384b1c8a0d863bf1be7d1f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
