{"version":"1.0","type":"rich","title":"Circles","description":"This example demonstrates the “Hello World” of a VizHub V3 Runtime Environment, showing a blank SVG canvas that fills the container’s width and height. The code uses D3’s `select` and `selectAll` with a data join of `[1]` to create an empty SVG element. The visualization highlights a minimal setup for continuous hot reloading with interactive widgets, serving as a template for building more complex charts. The entry point is the exported `main` function, which receives the `container` DIV as its argument, and the example lacks an `index.html` file, triggering the V3 Runtime.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/37b8cf916f7c48d1b988029aff18d9fc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
