{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank canvas fills the browser window, rendered as a single rounded rectangle using D3 v5's `select` and SVG `attr` methods. The visualization displays no data, only an empty, fixed-position SVG that adapts to the viewport's dimensions. The code imports `select` and `arc` from D3, though only `select` is used to create the static shape. The HTML loads `styles.css` for full-bleed layout and `bundle.js` to execute the drawing logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f31cf8363ac432a835100629ebed8e2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
