{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the entire browser viewport, serving as a minimal canvas with no data or marks rendered. The SVG element is dynamically sized to match the window dimensions using the D3v5 `select` API, and a single `rect` is appended with a 40-pixel corner radius. The complete visual result is a simple, frameless field, demonstrating basic SVG construction with D3’s selection and attribute-chaining methods against a fixed-position, full-screen body.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/17bac92a9a654516839635f797c64d86?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
