{"version":"1.0","type":"rich","title":"Bar Chart","description":"This example shows a blank page with a large, empty display area, as the title suggests a bar chart but no data or visual elements are rendered. The code sets up a basic HTML document with a centered body and loads D3 version 7 from a CDN. It defines an empty index.js file, so no chart is actually created. The example appears to be a starter template or a demonstration of how to begin using D3, rather than a working visualization, and includes an embedded YouTube video as instructional content.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/70665f6b566247edb43e1fd915d97cbd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
