{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This visualization displays a blank, rounded rectangle that fills the entire browser window. The SVG canvas is sized to match the viewport dimensions, and a single rectangle with a 40-pixel corner radius is appended to it. The code uses D3 v5’s `select` and `arc` imports, though only `select` is applied, while the styling relies on a fixed-position body with no margins or overflow. No data is loaded or rendered, leaving the canvas intentionally empty.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/96f15709f08d471192c318d05f565fb7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
