{"version":"1.0","type":"rich","title":"Hello World","description":"This example demonstrates the entry point for VizHub V3 applications, rendering a text element whose font size is controlled by a constant variable. The code uses the exported `main` function with a `container` DIV element, setting an HTML string with inline styles to display \"Hello World!\" at 217 pixels. Interactive widgets enable continuous hot reloading, allowing the font size to be adjusted dynamically. The runtime replaces the traditional `index.html` setup with this streamlined `main` function approach.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cb1918407adb42b7870d52fc49c74831?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
