{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A rounded, full-viewport rectangle fills the browser window, rendered as a single SVG `<rect>` with no data mapped to it. The example demonstrates a minimal blank canvas using D3 v6's `select` and `attr` methods to set the SVG's width and height from the document body's client dimensions. The rectangle's `rx` attribute softens its corners, while CSS fixes the body to prevent scrolling. The visualization shows only this simple geometric form, with no axes, marks, or interaction beyond the static shape.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2e4df76ae9b340509f62226504d20c2a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
