{"version":"1.0","type":"rich","title":"blank canvas","description":"A blank white canvas fills the entire browser viewport, rendered as a single rounded rectangle with no data or interaction. The example demonstrates the minimal setup for a D3.js v5 project using the `select` and `attr` APIs to size and style an SVG element. The code imports utilities from the `d3` module, sets the SVG dimensions to match the window’s `clientWidth` and `clientHeight`, and appends a rectangle with a 40-pixel corner radius. The page uses fixed positioning in CSS to eliminate margins and scrolling, creating an empty, immersive visual space.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/03666b44f4f84e37bfe9a8e3e3229fda?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
