{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the entire browser window. The visualization is a minimal SVG canvas that demonstrates the use of D3 v5's `select` method to resize an SVG element to the full width and height of the viewport. The code appends a single `rect` element with a 40-pixel corner radius, relying on the document's client dimensions. No data or interaction is present; the example focuses solely on the fundamental setup of an SVG drawing space.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4acbff47f20c40de89c0f53d0153c6f2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
