{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A nearly empty SVG canvas fills the entire browser viewport, containing only a single small rectangle with default black fill. The example demonstrates the most basic D3 setup: selecting the root `<svg>` element, reading the browser window’s dimensions, and setting the SVG’s width and height attributes accordingly. Using d3.select, the code appends one `<rect>` element with hardcoded width and height values, serving as a minimal starting point for further visualization development. The renderer is SVG with D3 v5, and the layout is fully responsive to the viewport size.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6530d625d5394f09a6538a4fa302a724?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
