{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example shows an interactive blank canvas where a single rounded rectangle fills the entire browser viewport. The visualization dynamically adapts to the window size by reading `document.body.clientWidth` and `clientHeight`, then applying these dimensions to both the SVG container and the rectangle via D3’s `select` and `attr` methods. The code uses D3 v6 and renders purely as SVG markup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/277f47dd9af848818868a193c4864a28?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
