{"version":"1.0","type":"rich","title":"Activity_6","description":"This example displays a simple message, “Hello VizHub!” centered on the page. The visualization uses D3.js v6’s `select` function to target a `div` with the id `message` and set its text content. The text is sourced from an ES6 module, `myMessage.js`, which exports the string. Styling is applied via a linked `styles.css` file, controlling the font size and alignment. The code demonstrates a minimal D3 setup without any data loading or complex rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5121603f3dbd4d198e8e5d23bde9e6fe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
