{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example demonstrates a blank, resizable canvas that fills the browser window, rendered as a rounded rectangle using SVG. It shows fundamental DOM manipulation with D3.js by selecting the empty `svg` element, setting its width and height to the viewport dimensions, and appending a `rect` with rounded corners. The code uses `d3.select` and `d3.append` from d3.v5, with the SVG size dynamically bound to `document.body.clientWidth` and `clientHeight`. The accompanying stylesheet fixes the body to prevent scrolling, ensuring the visualization always fits the screen.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/51cfff36ba5648a8910b080411176aad?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
