{"version":"1.0","type":"rich","title":"Activity_tutorial3.2","description":"This example renders the text “Hello VizHub!” in large, centered, 12em font using D3’s `select` to target a `div` with id `message`. The text content comes from an ES6 module, `myMessage.js`, which exports a string constant, demonstrating modular code organization. The page loads D3 v6 from a CDN and applies minimal CSS styling. The visualization simply displays static text, showing how D3 can manipulate the DOM for basic content placement.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fca4d0c21ebb4a7e8608b50ebb2e2b26?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
