+# Graph Export (SVG/PNG)
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Graph export service supporting SVG and PNG formats with options for scale, legend inclusion, metadata embedding, and custom background colors. Originally marked TODO in advisory but now implemented.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/graph/`
+- **Components**:
+  - `graph-canvas` (`src/Web/StellaOps.Web/src/app/features/graph/graph-canvas.component.ts`)
+  - `graph-explorer` (`src/Web/StellaOps.Web/src/app/features/graph/graph-explorer.component.ts`)
+  - `graph-filters` (`src/Web/StellaOps.Web/src/app/features/graph/graph-filters.component.ts`)
+  - `graph-hotkey-help` (`src/Web/StellaOps.Web/src/app/features/graph/graph-hotkey-help.component.ts`)
+  - `graph-overlays` (`src/Web/StellaOps.Web/src/app/features/graph/graph-overlays.component.ts`)
+  - `graph-side-panels` (`src/Web/StellaOps.Web/src/app/features/graph/graph-side-panels.component.ts`)
+- **Services**:
+  - `graph-accessibility` (`src/Web/StellaOps.Web/src/app/features/graph/graph-accessibility.service.ts`)
+- **Source**: Feature matrix scan
+
+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that has appropriate permissions
+  - [ ] Navigate to `/graph`
+  - [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
+- **Core verification**:
+  - [ ] Verify the visualization renders correctly with sample data
+  - [ ] Verify interactive elements (hover tooltips, click-to-drill-down) work
+  - [ ] Verify the visualization handles empty/minimal data gracefully
+- **Edge cases**:
+  - [ ] Verify graceful handling when backend API is unavailable (error state)
+  - [ ] Verify responsive layout at different viewport sizes
+  - [ ] Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
