{"version":"1.0","type":"rich","title":"Blank Layout","description":"A blank, blue full-window layout demonstrates the BlankLayout pattern for building responsive D3 visualizations. Using the d3.v7 library, the page fills the entire browser viewport through an absolutely positioned div, with dimensions calculated from `window.innerHeight` and `window.innerWidth`. The layout exposes a render chain that child functions can join for coordinated updates, and it tracks content dimensions during resize events. This minimal example shows how to establish a structured, method-chaining foundation for subsequent chart rendering operations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9e934a290a834a78af2f61dbe9509403?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
