+# Task ID: 41
+# Title: Implement Visual Task Dependency Graph in Terminal
+# Status: pending
+# Dependencies: None
+# Priority: medium
+# Description: Create a feature that renders task dependencies as a visual graph using ASCII/Unicode characters in the terminal, with color-coded nodes representing tasks and connecting lines showing dependency relationships.
+# Details:
+This implementation should include:
+
+1. Create a new command `graph` or `visualize` that displays the dependency graph.
+
+2. Design an ASCII/Unicode-based graph rendering system that:
+   - Represents each task as a node with its ID and abbreviated title
+   - Shows dependencies as directional lines between nodes (→, ↑, ↓, etc.)
+   - Uses color coding for different task statuses (e.g., green for completed, yellow for in-progress, red for blocked)
+   - Handles complex dependency chains with proper spacing and alignment
+
+3. Implement layout algorithms to:
+   - Minimize crossing lines for better readability
+   - Properly space nodes to avoid overlapping
+   - Support both vertical and horizontal graph orientations (as a configurable option)
+
+4. Add detection and highlighting of circular dependencies with a distinct color/pattern
+
+5. Include a legend explaining the color coding and symbols used
+
+6. Ensure the graph is responsive to terminal width, with options to:
+   - Automatically scale to fit the current terminal size
+   - Allow zooming in/out of specific sections for large graphs
+   - Support pagination or scrolling for very large dependency networks
+
+7. Add options to filter the graph by:
+   - Specific task IDs or ranges
+   - Task status
+   - Dependency depth (e.g., show only direct dependencies or N levels deep)
+
+8. Ensure accessibility by using distinct patterns in addition to colors for users with color vision deficiencies
+
+9. Optimize performance for projects with many tasks and complex dependency relationships
+
+# Test Strategy:
+1. Unit Tests:
+   - Test the graph generation algorithm with various dependency structures
+   - Verify correct node placement and connection rendering
+   - Test circular dependency detection
+   - Verify color coding matches task statuses
+
+2. Integration Tests:
+   - Test the command with projects of varying sizes (small, medium, large)
+   - Verify correct handling of different terminal sizes
+   - Test all filtering options
+
+3. Visual Verification:
+   - Create test cases with predefined dependency structures and verify the visual output matches expected patterns
+   - Test with terminals of different sizes, including very narrow terminals
+   - Verify readability of complex graphs
+
+4. Edge Cases:
+   - Test with no dependencies (single nodes only)
+   - Test with circular dependencies
+   - Test with very deep dependency chains
+   - Test with wide dependency networks (many parallel tasks)
+   - Test with the maximum supported number of tasks
+
+5. Usability Testing:
+   - Have team members use the feature and provide feedback on readability and usefulness
+   - Test in different terminal emulators to ensure compatibility
+   - Verify the feature works in terminals with limited color support
+
+6. Performance Testing:
+   - Measure rendering time for large projects
+   - Ensure reasonable performance with 100+ interconnected tasks
