v0.28.0

🆕 New Features

A lot of work done on Demo. The most important is that we are web now!

— How to try it:

1. Open the web demo and pick an example:
   • bipartite.json
   • tree_binary.json
2. Tweak Layout → Force-Directed/Hierarchical and play with Animation/Forces.
3. Click Export (top of the right panel) → choose “Include Layout” and/or “Node Positions”, then save to File or copy to Clipboard.
4. To import, go to the Import/Load tab → “Open” (or drag & drop a JSON file into the graph area). Your uploads appear under “User Uploads”.
5. On web, use Share to copy a deep link to the selected example.

• More useful keybindings were added (fit to screen (once), pan to graph)
• File import and export — planned to migrate to egui_graphs core in upcoming releases

Notes:

• New import/export features are in the demo UI only (not yet in the egui_graphs crate). Core support is planned.
• Positions are optional on import; if missing, nodes are placed in a circle initially.

🖥️ Demo

• File import:
  • User uploads with JSON schema support
    • Edges-only
    • Nodes and edges
    • Graph plus layout properties
  • Curated example graphs
  • Shareable deep links (see Highlights above)
• File export:
  • Optional include of layout and graph settings
• Demo UX improvements:
  • Debug overlay and instructional messages queue
  • Navigation keybindings and help button
  • Hierarchical layout controls and perf metrics panel

v0.27.0

🚀Highlights for v0.27.0

🆕 New Features

• Hover Interactions: Added from scratch! Graph nodes and edges now support hover effects, enabling more interactive and intuitive graph exploration.
• Custom Styling Hooks: Support for node and edge style hooks, allowing flexible and dynamic visual customization.
• Force-Directed Layout Enhancements:
  • Fruchterman-Reingold algorithm and extra forces for any force-directed graph.
  • Fast-forward feature for animated layouts.
  • Exposed force with an Extras wrapper for advanced usage.

🖥️ Demo & Usability Improvements

• Event filters, show/hide panels, and enhanced keybindings for better demo interactivity.
• Keybindings overlay replaced with a modern modal window.
• Debug overlay now displays steps count for animated layouts.
• Synchronized sliders and keybindings for a smoother demo experience.

🛠️ Fixes & Robustness

Full Changelog: v0.26.0...v0.27.0

v0.26.0

Highlights

• Added naive force-directed layout (Fruchterman–Reingold style) with adjustable simulation parameters.
• Demo now has a Force Directed panel (sliders + info tooltips) for live tuning.
• Refactored layout logic into smaller private helpers and added physics unit tests.
• Added layout state get/set API on GraphView for external control/persistence.
• Bumped egui to 0.32 (and refreshed related dev dependencies).
• Hardened Linux CI (installs required system libraries).
• README and doctests updated.

What's Changed

• Force-directed layout + tunable State.
• Demo: force-directed controls + tooltips.
• Layout step refactor (helpers private) + physics tests.
• Added GraphView::get_layout_state / set_layout_state.
• Larger debug overlay text in demo.
• CI: install ALSA & windowing deps on Linux.
• README: concise force-directed section.
• Doctest updated to use g() accessor.
• egui bumped to 0.32.

MRs

• Renaming and API stabilization by @blitzarx1 in #240
• Add Layout and LayoutState to public scope by @blitzarx1 in #248
• FDG layout, egui bump by @blitzarx1 in #249

Breaking Changes

• Graph no longer exposes its internal graph via a public field (graph.g); use accessor methods:
  • Before: graph.g.node_count()
  • After: graph.g().node_count()
  • For mutation: graph.g_mut()

Migration Notes

• Replace all direct field accesses .g. with method calls .g() / .g_mut().
• Force-directed layout imports:

  use egui_graphs::{LayoutForceDirected, LayoutStateForceDirected};

• Optional parameter control

  let mut state = view.get_layout_state::<LayoutStateForceDirected>().unwrap_or_default();
  // tweak fields...
  view.set_layout_state(state);
