{"version":"1.0","type":"rich","title":"Hello VizHub","description":"This example displays the text “Hello VizHub!” centered on a dark, gray background. It demonstrates a minimal D3.js setup, using the `select` function to target a `<div>` element and set its content. The page loads D3 v5 from a CDN and imports a custom ES6 module to supply the message string. Styling is handled with CSS, including a Google Fonts import for the Ubuntu typeface.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/40aff9c2d4b74b4d91b905f82437d9ad?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
