{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank slate of steel blue fills the browser window, sized to the full viewport via D3’s `select` and `.attr` methods. The example demonstrates the foundational rendering setup with d3.v5 and an SVG canvas, starting with an empty data-less rectangle that has rounded corners (`rx`). It references a `data.csv` file containing nominal GDP figures for ten countries, though the code itself does not yet visualize that data. The HTML loads D3 from a CDN and applies styling from an external stylesheet.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
