{"version":"1.0","type":"rich","title":"Blank Canvas","description":"An empty SVG canvas fills the browser window, displaying only a rounded rectangle that spans the full viewport. The example demonstrates the minimal setup required to render a blank visualization surface. The code uses D3 v5's `select` and `arc` imports to create an SVG container, then appends a `<rect>` element with its width and height set to the document body's client dimensions. The CSS fixes the body to prevent scrolling, ensuring the canvas remains static.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dc0e91daa40b46d9b35575bd0a1c64a3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
