{"version":"1.0","type":"rich","title":"responsiveVizContainer","description":"This example shows a gray inner rectangle centered within a scalable SVG container, with a ResizeObserver logging the container’s dimensions on every resize. The visualization uses D3’s `select`, `selectAll`, and `join` to bind and update SVG elements, while the `viz` function computes inner dimensions from configurable margins and sets the rectangle’s fill via the `innerRectFill` property. The code demonstrates basic responsive layout with a fixed margin structure and dynamic width and height values derived from the container’s client size.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/68b7e76fe9fb4156ab255bee47c603f6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
