{"version":"1.0","type":"rich","title":"Activity 7","description":"This example demonstrates how to build a simple D3.js application that displays a custom message in the browser. It shows a single text element, \"Hello VizHub!\", centered on the page using CSS styling, and serves as a minimal template for setting up a VizHub project. The code loads D3 v5 from a CDN and uses the `select` API to target a div element by ID, setting its text content from a locally imported ES6 module. The example highlights basic module imports, DOM manipulation, and integration of external libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/712666dda09a4d6d96bd84d04c21866c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
