 # @fusion-plugin-examples/dependency-graph
 
+## Unreleased
+
+### Patch Changes
+
+- Dependency graph auto-layout now switches orientation on tall or narrow viewports so dependency depth flows left-to-right on mobile/portrait layouts.

 - **Graph build**: edges are resolved only from `task.dependencies` as `source=dependent`, `target=dependency`
 - **Orphan dependency handling**: if a visible task depends on an excluded/missing dependency (for example `done`/`archived` after filtering), the missing edge is silently dropped and graph rendering continues without broken connectors

+- **Auto-layout**: Sugiyama-style layered layout (`computeAutoLayout`) groups nodes by dependency depth and spaces layers consistently, and flips orientation responsively (`height > width` or `width < 768`) so depth flows left-to-right on tall/narrow viewports
 - **Edge drawing**: SVG bezier curves from source bottom-center to target top-center, with arrowheads showing dependent → dependency direction
 - **Interaction**: drag-to-pan canvas background, scroll/two-finger pan, Ctrl/Cmd-wheel zoom, pinch-to-zoom with stationary midpoint, drag-to-reposition nodes, keyboard shortcuts, zoom toolbar, reset, and fit-to-graph
 - **Zoomed navigation reachability**: pan clamping now scales with the full rendered graph bounds (min/max node extents) at the active zoom level, so zooming in no longer traps off-screen content behind fixed viewport-only limits
