{"version":"1.0","type":"rich","title":"blank canvas","description":"An empty SVG canvas stretches across the viewport, containing no marks or data. The example demonstrates a minimal starting point for D3-based visualization work. It uses d3.select to reference the SVG element and computes the available dimensions from document.body.clientWidth and document.body.clientHeight, though the code to set the SVG size and append a rectangle is commented out. The page relies on d3.v5 and styles the body to fill the screen with hidden overflow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b13bf2d3634f4863a807175eee827e39?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
