{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the entire browser viewport, creating a minimal and featureless visual canvas. The SVG element is sized to the full dimensions of the document body, and a single `rect` with a corner radius (`rx`) is appended to it. The example demonstrates a basic setup using D3's selection API (`select`) and attribute setters (`attr`) to establish a static, empty drawing area. The design relies on a fixed, full-screen CSS layout and a D3 script (`bundle.js`) to render the SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2a0a5f6b2f2a400da39026ae1d13788f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
