I’ve been working on a modern web-based viewer for hierarchical data, inspired heavily by Krona. It’s called Jowna - https://github.com/owebeeone/jowna

While Krona is excellent, I wanted a solution that integrates better with modern React/Web stacks and doesn't require Perl to generate snapshots. Jowna allows you to visualize hierarchical data directly in the browser. Project data is stored in the browser.

Key features:

• Pure browser based (React implementation. No need for perl)

• Zoomable sunburst visualization similar to Krona.

• Search and crumb-trail navigation.

• HTML download for sharing (and project files too)

It's early days so use with caution. I’ve tried to reach feature parity with Krona, though some edge cases remain. I would love for the community to test it with their datasets and let me know what breaks. I only started on this 2 days ago so I'm sure some things are broken.

Enjoy
