{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded-corner rectangle fills the entire browser viewport on a fixed, overflow-hidden page. The visualization is an empty canvas, showing no data or marks, only a single SVG `rect` element with a large corner radius. It uses D3 v5’s `select` API to target the SVG element and set its width and height to the document body’s client dimensions. The rendering is purely SVG, with no axes, labels, or interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4e60bc0e783146b3b77d5f6d29236560?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
