# Graph Settings Implementation Summary
 | 
						|
 | 
						|
## ✅ Implementation Complete
 | 
						|
 | 
						|
A comprehensive Graph Settings feature has been successfully implemented for ObsiViewer, providing full Obsidian compatibility for graph customization.
 | 
						|
 | 
						|
## 📦 What Was Built
 | 
						|
 | 
						|
### Core Architecture
 | 
						|
 | 
						|
#### 1. **Type System** (`src/app/graph/graph-settings.types.ts`)
 | 
						|
- `GraphConfig` interface matching Obsidian's graph.json structure
 | 
						|
- `GraphColor` and `GraphColorGroup` types for color management
 | 
						|
- Color conversion utilities (HEX ↔ RGB Integer ↔ RGBA)
 | 
						|
- Validation and bounds checking for all numeric values
 | 
						|
- Default configuration constants
 | 
						|
 | 
						|
#### 2. **Service Layer** (`src/app/graph/graph-settings.service.ts`)
 | 
						|
- Load/save configuration from `.obsidian/graph.json`
 | 
						|
- Debounced writes (250ms) to prevent excessive I/O
 | 
						|
- External file change detection (2-second polling)
 | 
						|
- Section-specific and global reset functionality
 | 
						|
- Signal-based reactive state management
 | 
						|
- Conflict resolution with revision tracking
 | 
						|
 | 
						|
#### 3. **Runtime Adapter** (`src/app/graph/graph-runtime-adapter.ts`)
 | 
						|
- Converts `GraphConfig` to `GraphDisplayOptions`
 | 
						|
- Applies filters (search, tags, attachments, orphans, unresolved)
 | 
						|
- Processes color groups with query matching
 | 
						|
- Translates Obsidian ranges to d3-force parameters
 | 
						|
- Node coloring based on tag/file/path queries
 | 
						|
 | 
						|
#### 4. **UI Components**
 | 
						|
 | 
						|
**Settings Button** (`ui/settings-button.component.ts`)
 | 
						|
- Gear icon (⚙️) in top-right corner
 | 
						|
- Smooth rotation animation on hover
 | 
						|
- Keyboard accessible (Enter/Space)
 | 
						|
- Dark mode support
 | 
						|
 | 
						|
**Settings Panel** (`ui/settings-panel.component.ts`)
 | 
						|
- Slide-over panel (400px desktop, full-screen mobile)
 | 
						|
- Collapsible sections with persist state
 | 
						|
- Close on Esc key, backdrop click
 | 
						|
- Reset all/reset section buttons
 | 
						|
- Focus trap when open
 | 
						|
 | 
						|
**Section Components**:
 | 
						|
- **Filters** (`sections/filters-section.component.ts`)
 | 
						|
  - Search input
 | 
						|
  - Tag/Attachment/Orphan/Unresolved toggles
 | 
						|
  
 | 
						|
- **Groups** (`sections/groups-section.component.ts`)
 | 
						|
  - Color group list with color picker
 | 
						|
  - Query input (tag:/file:/path:)
 | 
						|
  - Add/Duplicate/Delete actions
 | 
						|
  - Help text with examples
 | 
						|
  
 | 
						|
- **Display** (`sections/display-section.component.ts`)
 | 
						|
  - Arrows toggle
 | 
						|
  - Text fade/Node size/Link thickness sliders
 | 
						|
  - Animate button
 | 
						|
  
 | 
						|
- **Forces** (`sections/forces-section.component.ts`)
 | 
						|
  - Center/Repel/Link force sliders
 | 
						|
  - Link distance slider
 | 
						|
  - Real-time value display
 | 
						|
 | 
						|
### Backend Integration
 | 
						|
 | 
						|
#### Server Endpoints (`server/index.mjs`)
 | 
						|
 | 
						|
**GET /api/vault/graph**
 | 
						|
- Load graph configuration
 | 
						|
- Returns `{ config, rev }`
 | 
						|
- Creates default config if missing
 | 
						|
 | 
						|
**PUT /api/vault/graph**
 | 
						|
- Save graph configuration
 | 
						|
- Supports `If-Match` header for conflict detection
 | 
						|
- Atomic writes (temp file + rename)
 | 
						|
- Auto-backup to `.bak` file
 | 
						|
- Returns new revision
 | 
						|
 | 
						|
### Frontend Integration
 | 
						|
 | 
						|
#### Updated Components
 | 
						|
 | 
						|
**graph-view-container.component.ts**
 | 
						|
- Integrated settings button and panel
 | 
						|
- Applied filters to graph data
 | 
						|
- Computed display options from config
 | 
						|
- Applied color groups to nodes
 | 
						|
- Maintained backward compatibility with old panel
 | 
						|
 | 
						|
**graph-view.component.ts**
 | 
						|
- Added `nodeColors` to `GraphDisplayOptions`
 | 
						|
- Implemented `getNodeColor()` method
 | 
						|
- Dynamic node coloring based on groups
 | 
						|
- SVG circle fill from color map
 | 
						|
