{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the viewport, its size derived from the browser’s client height and width. The piece uses D3 v5’s `select` to target the SVG element and appends a single `rect` with corner radius, creating a minimalist visual that demonstrates spatial framing without data. The rendering is pure SVG, styled by CSS to be fixed and fullscreen, leaving the canvas empty for the viewer’s interpretation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b1babd3042334d099f62bb280c5afd01?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
