{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A nearly blank canvas renders as a single rounded rectangle filling the browser viewport, sized dynamically to the window dimensions. The example demonstrates minimal D3.js usage with the `select` function to query an SVG element, then applies width and height attributes and appends a `rect` with a fixed corner radius. The visualization is purely geometric, with no data or interaction, serving as a template for React-based D3 projects. The styling enforces a fixed full-screen layout using CSS body rules.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d0af316480141739f832146bdde6f29?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
