{"version":"1.0","type":"rich","title":"Activity6_Task2_Tutorial","description":"This example demonstrates a minimal D3.js visualization that displays a centered text message using the D3 selection API. The code imports the `select` function from D3 and sets the text content of a `<div>` element with the ID `message` to ‘Hello VizHub!’. Styling for the text is provided through an external CSS file that specifies center alignment and a large font size. The implementation uses the `d3.select` method to target the DOM element and the `.text()` method to populate it with the imported message string.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f7358071947b4d4d93f82ec86b94787e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
