{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the entire browser viewport with a solid color, creating an empty canvas within an SVG element. The example demonstrates the minimal setup required to render a shape using D3 v5, selecting the SVG with `d3.select` and appending a `rect` element whose dimensions are derived from `document.body.clientWidth` and `clientHeight`. The body is fixed with hidden overflow, ensuring the visualization occupies the full screen without scrollbars. This serves as a foundational template for more complex D3 projects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dbf609ccbe1a46b5b73446ad4a621c29?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
