{"version":"1.0","type":"rich","title":"activity 6","description":"This example demonstrates how to load D3.js from a CDN and use ES6 module imports to display a simple text message in the browser. The code imports the `select` function from D3 and a local `message` constant from `myMessage.js`, then sets the text of a `div` element with the ID `message` using `select('#message').text(message)`. The page renders a large, centered \"Hello VizHub!\" heading, styled via an external CSS file. It also includes commented-out JavaScript examples, such as a variable declaration and a regular expression, to illustrate basic syntax.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e105aad18a894d508043a75a014a81df?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
