{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the entire browser viewport as a standalone SVG canvas. The visualization demonstrates a minimal setup where no data or marks are present, only a styled background shape. The code uses D3 v5 to select the SVG element, set its width and height to the document body’s client dimensions, and append a single `rect` with a 40-pixel corner radius. No axes, scales, or interactions are defined, making this a static, empty canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b67deb82920474587d5e7f13dc641f8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
