{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded-rectangle canvas fills the browser window as the sole visual output. The example demonstrates a minimal SVG setup where no data is loaded or drawn beyond the background shape. It uses D3 v5 selections to size the SVG to the viewport and appends a single rectangle with rounded corners. The styling is handled by a separate stylesheet, while the rendering relies entirely on D3’s `select` and `attr` methods for SVG manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/331cd74a94844b7f933a457c197f7330?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
