{"version":"1.0","type":"rich","title":"Activity6_Task3","description":"This example displays a centered, large-scale “Hello VizHub!” message using D3.js to manipulate the DOM. The code imports D3’s `select` function and a local ES6 module, demonstrating modular JavaScript and library integration. It also includes a regular expression and a constant variable, though these have no visual output. The styling is handled via an external CSS file, setting the text alignment and font size. The rendering approach is a simple static text update, with D3 loading from UNPKG in the HTML.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c818908c69bf416db2bb49738fb3ea04?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
