{"version":"1.0","type":"rich","title":"circle","description":"This example shows a single green circle with a blue stroke rendered on a blank SVG canvas. The visualization demonstrates basic D3 version 7 usage by importing the `select` function from the `d3` module and updating the page text. The circle is defined directly in the HTML markup with fixed `cx`, `cy`, `r`, and fill attributes, while SVG provides the rendering surface. The code illustrates how to begin a D3 project, though it does not yet bind any external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0204e48b135340c0823fef417e4231ac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
