{"version":"1.0","type":"rich","title":"Activity_Tutorial2","description":"This example demonstrates a minimalist text message display. It renders the phrase “Hello VizHub!” centered on the page using the D3.js `select` function to target a `div` element and set its text content. The styling, defined in CSS, applies a 12em font size and text alignment. The code imports the message from a separate ES6 module, `myMessage.js`, and uses D3 v6 loaded from a CDN. The data source is a static string, with no dynamic data or interactive behavior present.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2bd459016aad4dd68739721b367841a4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
