{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank SVG canvas fills the browser viewport, displaying nothing but a single rounded rectangle that matches the window's dimensions. The visualization demonstrates the foundational setup of a D3 project by importing the `d3` library and appending a basic shape element. Using `d3.select` on an empty SVG, it dynamically sets the width and height attributes based on the document's client dimensions, then adds a `rect` with a 40-pixel corner radius. The code relies on D3 v5 and a bundled JavaScript file, with CSS positioning the body to cover the entire viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/84c539b70d3145ecb8a6560e3fded51e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
