{"version":"1.0","type":"rich","title":"Activity 6","description":"This example demonstrates a minimal D3.js setup that dynamically updates the text content of an HTML element. It loads D3 v5 from a CDN and uses the `select` API to set the message \"Hello VizHub!\" inside a styled div, with modular code imported from a local ES6 module. The visualization also includes a regular expression and variable declaration, though these do not affect the output. The page styling is defined in a separate CSS file with large centered text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/668b0ede63204443863225b0948d0337?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
