{"version":"1.0","type":"rich","title":"bar chart practice","description":"This example creates an abstract geometric composition using D3.js within a React project. It draws 100 horizontal and vertical bars across the full screen, then applies two distinct circular masks to create cross-shaped and bordered effects. The SVG rendering uses D3’s `select`, `range`, and `join` APIs to generate the rectangles, while two custom masks—one with a black background and white circle, another inverted—produce the visual contrast against the dark background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a4e77f475cb34a4b811ee71b5950d1a1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
