{"version":"1.0","type":"rich","title":"activity 6","description":"This example demonstrates how to set up a minimal VizHub app that loads D3 from a CDN and uses ES6 modules for local code. It shows a simple webpage with the text \"Hello VizHub!\" displayed prominently, centered via CSS in a div. The code uses `import { select } from 'd3'` to manipulate the DOM and `import { message } from './myMessage'` to bring in a local string constant. The rendering approach is straightforward text content set with `select('#message').text(message)`, with no data source involved.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a184d6e9e23e4ff0b807a1f75364c494?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
