Project mention: Show HN: Orbit – A CSS radial UI composer framework | news.ycombinator.com | 2024-08-08
Glad you like it! Several years ago, I wrote my first project, Zircle UI, which mixed zoomable navigation with circular UI. It was not flexible at all, but I enjoyed it and learned a lot from this experience. Then, I decided to split Zircle into two independent parts: Orbit for radial UI (I mean, not constrained to circular shapes), and Zumly, a JS zoomable WIP engine (https://github.com/zumerlab/zumly). While you can use both projects together, they can also be used independently
