{"version":"1.0","type":"rich","title":"Blank canvas","description":"A blank, interactive canvas fills the browser window, rendered as a single rounded rectangle spanning the full viewport. The example demonstrates a minimal setup for a D3.js visualization, using `d3.select` to target the SVG element and setting its dimensions based on the document body's client width and height. The code imports `select` and `arc` from D3 v5, though the latter is not used here. The SVG background is drawn via `.append('rect')`, with the page's fixed positioning and margin removal handled by the accompanying CSS file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5cf58198c4bf4a99a40d211419bf0f80?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
