{"version":"1.0","type":"rich","title":"activity 6","description":"This example displays the text “Hello VizHub!” centered prominently on the page using D3.js. The code imports the `select` function from D3 and applies it to the `#message` div, setting its text content from a separate ES6 module. The styling uses CSS to center the message and set its font size to 12em. While the repository includes a minimal HTML shell and styling, the visualization itself is purely text-based, demonstrating basic DOM manipulation with D3 v6.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e268fed34eba487ea87238ccd0d02199?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
