{"version":"1.0","type":"rich","title":"test","description":"This example demonstrates a minimal \"Hello World\" setup for the VizHub V3 runtime, showing how a `main` function initializes a container with an interactive font-size widget and appends an SVG text element. The code uses D3.js to select the body and append an SVG, then adds a text node, while the container’s inline HTML relies on CSS styling. It highlights the runtime’s support for direct DOM manipulation and real-time property editing via Alt-drag. The SVG rendering approach is explicit, with D3’s `select` and `append` methods driving the visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/28a3450098e74e58bba8509d77cd2bd7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
