{"version":"1.0","type":"rich","title":"Activity-6(Task4)","description":"This example demonstrates a minimal D3.js visualization that renders a static text message, “Hello VizHub!”, into a centered HTML div. It shows how to set up a VizHub project by loading D3 v5 from a CDN and importing both the `select` function from the `d3` module and a local ES6 module. The code uses `select('#message').text(message)` to update the DOM, with styling provided by CSS. It also includes a regular expression and variable declaration, though these do not affect the visual output.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6a5d1ee849d64e88999f98a0c55eb02d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
