{"version":"1.0","type":"rich","title":"Population","description":"This example displays the text “Hello D3 version 7” in the center of the page at a massive font size. It demonstrates basic DOM manipulation using D3’s `select` method to target the `body` element and set its text content. The visualization loads D3 v7 from a CDN and updates the page’s existing `body` element, relying on the bundled `index.js` for the dynamic text assignment. No data fetching or complex rendering occurs, only a simple text replacement within the HTML document.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c5cf0912ade543c8b59cd3d41a50c21e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
