{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example shows an empty, full-window SVG canvas with a rounded rectangle filling the entire viewport. The visualization resizes to the browser’s current dimensions, logging the width to the console. It uses D3 v6’s `select` function to target the SVG element and append the rectangle, while CSS `body` styles fix the document to the viewport and hide overflow. The code demonstrates a minimal starting point for a blank canvas, with the rounded corners (`rx` attribute) subtly framing the otherwise empty space.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/75c5a0c1ee5b4898b7d4d50ca4b24daa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
