v0.4.0

What's new

3 new diagram types (13 total):

• Timeline: vertical event lists with sections and details
• Kanban: column-based task boards with cards
• Quadrant chart: 2x2 priority/risk matrices with plotted points

5 solid-background themes: gruvbox, monokai, dracula, nord, solarized with filled region colors, depth shading for kanban cards, and per-section coloring across kanban/timeline/quadrant

JSON ingest (--json): pipe structured data directly

echo '{"Python":45,"Go":30}' | termaid --json pie
du -d1 -k /var | termaid --json treemap

CLI: --demo, --themes, quoted edge labels fix, padding_x/gap threaded through 7 renderers

v0.3.0

What's new

Rendering engine overhaul -- all 5 known rendering bugs are fixed:

• Junction characters now derived from direction bitfields instead of a lookup table
• Crossing edges get extra routing space via automatic gap expansion
• Overlapping arrows spread across node borders
• Subgraphs no longer overlap when cross-boundary edges exist
• Edge labels from different edges no longer merge onto the same line

New diagram type: mindmaps

          ╭─ Design ──╭─ Wireframes
          │           ╰─ Mockups
Project ──├─ Development ──╭─ Frontend
          │                ╰─ Backend
          ╰─ Testing

CLI improvements:

• --width N -- max output width with automatic compaction
• -o FILE -- write to file
• --show-ids -- debug node ID/label mapping
• --no-auto-fit -- disable terminal width auto-compaction
• NO_COLOR environment variable respected

Code quality:

• Layout engine split from 1 file (1095 lines) into 5 focused modules
• 1066 tests, 0 failures
• Gallery of all 78 fixture diagrams in docs/gallery.md

v0.2.1

Add --gap flag for compact diagram spacing. Use --gap 1 or --gap 2 to fit wide LR diagrams in narrower terminals.

v0.2.0

Add pie chart and treemap support (9 diagram types)

v0.1.3

• Add --tui flag for interactive TUI viewer (pip install termaid[tui])
• Update demo GIF with pipe and TUI examples
