{"version":"1.0","type":"rich","title":"Hz what it is","description":"This example renders a single black circle centered on the page using React. The `Circle` component accepts `cx`, `cy`, `r`, and `fill` props, logging the `cx` value to the console on each render. The circle is drawn with JSX inside the component and mounted to the DOM via `ReactDOM.render`. Styling hides page margins and overflow, while React and ReactDOM are loaded from the unpkg CDN.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4e83cf8af7a84be281e4e4821bb2c54b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
