{"version":"1.0","type":"rich","title":" HELLO WORLD","description":"This example demonstrates the fundamental structure of a VizHub V3 visualization, rendering a red \"Hello World!\" message at a fixed pixel size. It shows how the exported `main` function accepts a `container` DIV element and writes directly to its `innerHTML` property. The code highlights the runtime's interactive widget support, where holding the Alt key and dragging the numeric `fontSize` value enables continuous hot reloading. No external libraries are used beyond the VizHub V3 runtime environment itself.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/74bffd7a47864e308020d8683dc0b811?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
