{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank SVG canvas is filled with a single gray rectangle that spans the full width and height of the viewport, creating a minimalist visual effect. The example demonstrates the basic structure of a D3.js v5 project, using `d3.select` to access the SVG element and `svg.append` to add a `rect` element. The rectangle’s width is set twice in the code, while its height remains unspecified, leaving the shape incomplete. This serves as a starting point for understanding SVG rendering with D3’s declarative API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/98961c16ab5946dda90e475fb72796e3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
