{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the entire browser viewport, offering an empty visual canvas. The example demonstrates the minimal setup for a D3.js v5 visualization using SVG rendering, where the page dimensions are read directly from the document body and applied to the SVG element. The code relies on d3.select to target the pre-existing svg tag and appends a single rect with corner radius. No data drives the display; the focus is purely on establishing a flexible, full-window drawing surface.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e277ffd0d50b4ec6b3e57abcc25a1ff8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
