{"version":"1.0","type":"rich","title":"vizFunctionConcept","description":"This example demonstrates a minimal D3.js visualization that renders a single scaled rectangle within an SVG container. The code uses D3's `select` and `join` APIs to create and update the SVG elements, with the rectangle’s dimensions calculated from the container’s width and height minus specified margins. The visualization highlights a basic structural pattern—an outer canvas with a centered inner rectangle filled with a gray color—suitable as a starting point for thematic customization. The source code is organized into separate `index.js` and `viz.js` modules, with the latter accepting configuration options for layout and styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/50c82fdb57a343b7ba26b04ba71a2f56?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
