{"version":"1.0","type":"rich","title":"A6_Q4","description":"This example demonstrates the minimal \"Hello World\" starter template for the VizHub V3 runtime, displaying a single text string centered within an HTML container. The exported `main` function receives a `container` DOM element and sets its inner HTML directly, with font size controlled by a hardcoded numeric value that the user can adjust interactively by Alt-dragging in the editor. It shows how the runtime hot-reloads changes in real time, using no external libraries beyond the browser’s built-in DOM APIs. The rendering approach is plain HTML and CSS within the container element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/522326ed8c32476799a6022445aff258?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
