{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example displays a blank, rounded rectangle that fills the entire browser viewport against an empty page. Built with D3 v5 and rendered as SVG, the code uses `select` and `append` to create a single `rect` element. The visual’s dimensions are derived directly from `document.body.clientWidth` and `clientHeight`, and the CSS fixes the body to prevent scrolling. No data or interaction is present; the piece functions purely as a minimalist canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/194a79821c7f4f94b4a3df4d33f56424?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
