{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank rectangular canvas fills the browser viewport, rendered as a single rounded rectangle. The visualization demonstrates the foundational step of setting up an SVG drawing surface with D3 v5. The code uses `d3.select` to access the SVG element and sets its width and height attributes based on the document body’s dimensions. A `rect` element is appended and styled with `rx` for rounded corners, creating an empty, minimal display with no additional data or interactive elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e07f6d887eb9450680a3423963084cbb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
