{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example presents an empty, rounded rectangle that fills the entire browser viewport as a blank canvas. The visualization uses D3 v5 to select the SVG element and dynamically set its dimensions based on the document body’s client width and height, then appends a single rectangle with a 40-pixel corner radius. The SVG rendering approach relies on the D3 `select` and `append` API, while the fixed-position CSS ensures the graphic stays locked to the screen edges without scrollbars.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d55e6c7cabcb4e3ea92c57b721d2289c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
