{"version":"1.0","type":"rich","title":"Smiley face part 1","description":"This example shows a single gray circle centered in an SVG canvas, rendered using React and D3 v7. The circle is positioned statically at the midpoint of the 960×500 viewport, with no interactive data binding. It demonstrates React’s `ReactDOM.render` method to mount a functional component that returns an SVG `<circle>`, while a separate static SVG in the HTML displays two additional unfilled circles. A mouse move handler logs events to the console, but no visual feedback occurs. The rendering relies on React’s virtual DOM and D3’s SVG utilities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/56cf8b270afe477a80c2fc2178e410e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
