{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example demonstrates a blank, interactive-free canvas that fills the browser viewport with a single rounded rectangle. Using the D3.js library’s `select` function, it dynamically retrieves the body’s client width and height, then sets the SVG’s dimensions accordingly and appends a `rect` element whose corners are rounded via the `rx` attribute. The visualization relies on D3 v5 and SVG rendering, with styling provided by a fixed-position CSS layout that ensures the canvas remains fully visible.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/700439e612784684bfca2d9761a3640e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
