{"version":"1.0","type":"rich","title":"activity6","description":"This example demonstrates a minimal D3.js setup within the VizHub framework. It displays the text \"Hello VizHub!\" centered on a white background using a large, bold font. The code imports the `select` function from D3 v5 and a custom message from a local ES6 module, then uses `select('#message').text(message)` to set the DOM element's content. The page loads D3 from a CDN and applies styling from a linked CSS file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/309f2c5349d046579b854279807aa222?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
