{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example demonstrates an empty SVG canvas that fills the browser window and displays a rounded rectangle as its only visual element. The code uses d3.select to target the SVG element and sets its width and height to match the available viewport dimensions, then appends a rect with a corner radius. The D3 v6 select method and attribute chaining handle the SVG drawing, while the fixed CSS positioning ensures the canvas remains anchored to the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8294b2394c1a4dd09046344d840cbcef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
