{"version":"1.0","type":"rich","title":"Blank Canvas","description":"An empty SVG canvas fills the browser viewport with a single rounded rectangle, creating a blank slate for visualization. The example demonstrates a minimal React setup where D3 v5 selects the root SVG element and sets its dimensions to match the window. Using the `d3.select` API, the code appends a `rect` element with a 40-pixel corner radius to the SVG, styling it as a softly rounded full-screen backdrop. The rendering relies solely on SVG primitives, with no data binding or interaction logic present.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7e2f7ae7a5cf4fbeb1d125c0aeb5f651?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
