{"version":"1.0","type":"rich","title":"blank canvas","description":"A blank, rounded rectangle fills the entire browser window, created as a single SVG `<rect>` element. The visualization calculates the canvas dimensions from the document body's client height and width, applying a 40-pixel corner radius to the shape. The code uses D3 v5's selection API (`d3.select`) to target the SVG element and chain attribute assignments for sizing and styling. The example demonstrates a minimal SVG rendering pipeline with D3, where the resulting graphic is purely a static, empty canvas with no data or interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/23f9e6fa922641fcb2da75bdbaa68a3d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
