{"version":"1.0","type":"rich","title":"Blank canvas","description":"An empty, rounded-rectangle SVG canvas fills the entire browser viewport. The example demonstrates a minimal D3 v5 setup where the `select` and `arc` functions are imported but unused, leaving the visualization intentionally blank. The code sets the SVG’s width and height attributes based on `document.body.clientWidth` and `clientHeight`, then appends a single `rect` with a 40-pixel corner radius. No data or interaction is present, showing the starting point for a blank visualization project.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d566907cc72f4a94b94fd05ada746856?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
