{"version":"1.0","type":"rich","title":"Activity 6_Question 2","description":"This example demonstrates the VizHub V3 Runtime Environment’s “Hello World” starting point, showing how a simple text string can be rendered with dynamic styling. The code exports a `main` function that receives a `container` DIV, sets its `innerHTML` to display “Hello World!”, and enables interactive editing—users can Alt-drag the `fontSize` variable to change the text size in real time. The visualization uses no external libraries, relying solely on the runtime’s continuous hot reloading to update the DOM.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/73acc0c914cc4e30abb03b0b5657e050?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
