{"version":"1.0","type":"rich","title":"Activity 7.1","description":"This example demonstrates how to build a simple VizHub project by loading D3 v5 from a CDN and importing local ES6 modules. It displays the text “Hello VizHub!” centered in a large font using the `d3.select` API to set the content of an HTML div element. The code uses `import { select } from 'd3'` and a custom module `myMessage.js` to export the message string, showing basic module composition. The page is styled with a CSS file that centers the message and sets its font size. The visualization is minimal, focusing on tooling and module patterns rather than data rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9da20b9d5c404a6687b7977bc364c703?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
