{"version":"1.0","type":"rich","title":"Activity 7.1","description":"This example displays a simple text message, \"Hello VizHub!\", centered on the page with a large font size. The code imports the `select` function from D3.js to target the `#message` div and sets its text content using the imported `message` string. It demonstrates a basic D3 selection and DOM manipulation pattern, with the message defined as an ES6 module export in `myMessage.js`. The styling is handled by external CSS, and the application runs entirely in the browser.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/243b6887f81c422cb9e38b37c72cedeb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
