{"version":"1.0","type":"rich","title":"Hello VizHub","description":"This example demonstrates a minimal D3.js visualization that displays the text “Hello VizHub!” in a large, centered Ubuntu font on a dark blue background. It shows how to structure a simple web page using HTML, CSS, and ES6 modules, with D3’s `select` method updating the text content of a designated div element. The page imports D3 from a CDN and uses a local module to export the message string, illustrating basic data-binding and modular code organization within the VizHub framework.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9e8c8f7f4929461dab0d2e8ee51c63e2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
