{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the browser window, rendered as an SVG canvas. The visualization demonstrates a minimal scene setup using D3 v6, where the page dimensions define the SVG’s width and height. The code selects the SVG element, sets its attributes, and appends a single styled rectangle via D3’s `select` and `append` methods. No data is loaded or mapped; the focus is purely on establishing an empty visual field with the d3 library and inline SVG markup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/43a7df9864d248f7b07ca4d8d78b3103?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
