{"version":"1.0","type":"rich","title":"activity_8tutorial1","description":"This example demonstrates a minimal VizHub template that loads D3 via CDN and renders a text message. It shows how to import functions from D3’s `select` API and a local ES6 module exporting a string constant. The `index.html` page contains a single `div` element, which D3 populates with the message, while `styles.css` centers the text at a large font size. It also defines an unused variable and regular expression in the main script.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ef216586b1d442c8bf8aca0dde5f17f5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
