{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the entire 960 by 500 pixel SVG canvas, demonstrating a minimal starting point for visualization projects. The example uses D3 v5’s `select` method to target the SVG element and set its dimensions, then appends a single `rect` with a 40-pixel corner radius. The accompanying CSS fixes the body to the viewport edges and hides overflow, ensuring the canvas occupies the full screen without scrollbars. This serves as a template for building more complex D3-based graphics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b6c4b0a683d147438f9dfc18772083d4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
