{"version":"1.0","type":"rich","title":"Hello D3","description":"This example shows a simple introductory D3 visualization that replaces the entire body content with the text “Hello d3 v6.” It demonstrates the most basic use of D3’s `select` method to target an element and set its text content. The HTML page loads D3 v6 from a CDN and uses a CSS class to style the message with a large, centered font. The rendering is purely text-based, with no data or graphical marks involved.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6890e2e52ecb4617bad58f9a0b0fd5cc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
