{"version":"1.0","type":"rich","title":"Hello VizHub","description":"This example displays a bold, centered “Hello World!” message on a dark background, showcasing the fundamental capabilities of D3.js and VizHub. The visualization uses D3’s `select` method to target the DOM element with the ID `message` and update its text content. The code imports a custom module, `myMessage.js`, which exports the message string, demonstrating modular JavaScript development. Styling is applied via an external CSS file that imports the Ubuntu font from Google Fonts, sets a dark theme, and centers the large, 12em text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7ad0dd4a8d864edc885e6f1ffc9a216e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
