Show HN: Notesium, Markdown Notes in Vim with an Obsidian-Like Graph View (github.com)

Notesium aspires to support the concepts of Evergreen notes and Zettelkasten, with bi-directional links at its core, essentially acting as an indexer. It integrates with Vim via FZF for link insertion, listing, previewing, fuzzy searching, etc., and supports a force-graph view (D3.js) with multiple clustering options.

Created to scratch my own itch, it's a little opinionated (rationale documented in README), and should be considered experimental. I'd be interested to hear what you think.
