{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, full-viewport SVG canvas is created, filling the browser window with a single rounded rectangle. The example demonstrates a minimal starting point for a visualization, with no data or marks drawn. The code uses D3 v5’s `select` function to target the SVG element, sets its dimensions to the document body’s client width and height, and appends a `rect` with a 40-pixel corner radius, all styled by a fixed-position CSS layout that removes margins and scrollbars.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/abf5e773bb3c438592fdc53faa4f6868?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
