{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example displays a single rounded rectangle filling the entire browser viewport, adapting its dimensions to the window’s client area. The visualization uses D3 v6 selections via the `d3.select` API to target the SVG element, then appends a `rect` with corner radius (`rx`) set to 40. The SVG’s width and height are derived from `document.body.clientWidth` and `document.body.clientHeight`, with CSS fixing the body to the screen edges and hiding overflow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/53496daf022e4ef1a57c0c5f2c1dd741?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
