{"version":"1.0","type":"rich","title":"Fork of D3 Starter","description":"This example demonstrates how to render three black rectangles in an SVG canvas using a React component with D3 version 7. The code uses the `select` function from D3 to bind an array of three data objects to appended rectangular elements, positioning them diagonally via `attr(\"x\")` and `attr(\"y\")`. It shows a basic data join pattern where the enter selection creates rectangles, highlighting the integration of React refs (via `useRef`) with D3’s imperative DOM manipulation inside a `useEffect` hook.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/68c50402eb804b4eb1a1070aeff5678f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
