{"version":"1.0","type":"rich","title":"Activity6_Question2_1","description":"This example demonstrates the VizHub V3 runtime environment’s \"Hello World\" template, which serves as a blank slate for interactive coding with continuous hot reloading. It renders a single line of text whose font size can be adjusted live by holding the Alt key and dragging the numeric value directly in the editor. The code exports a `main` function that takes a container element and sets its inner HTML, showing how the platform eliminates the need for an `index.html` file. The visualization uses no external libraries, relying solely on the container’s `clientWidth` and `clientHeight` properties for layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b0047cf3cdca478992bb3379bac71b2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
