{"version":"1.0","type":"rich","title":"Hello VizHub","description":"A minimal D3.js example renders a centered text message in the browser using the `select` method to update the DOM. The message text is imported from a local ES6 module and displayed via an HTML `div` element styled with CSS. This demonstrates fundamental VizHub concepts: linking D3 v5 from a CDN, modular JavaScript imports, and separating styles into an external stylesheet. The visualization shows a simple \"Hello World!\" greeting without any data or interactive behavior.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/34dc0a2c90274200b51d6e9d6e5c2639?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
