{"version":"1.0","type":"rich","title":"Activity6_Task1","description":"This example demonstrates a simple D3.js visualization that displays the text \"Hello VizHub!\" centered on the page. The code initializes a D3 selection on the `#message` div and sets its text content using the `select` method. Styling is applied through CSS to center and enlarge the text. The visualization uses D3's selection API to manipulate the DOM element, with the message imported from a separate ES6 module. The implementation relies on D3 v6 loaded from a CDN and follows a basic single-view pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
