# Analytics Package - Goals, Metrics, and Insights

## Purpose
Tracks goals, metrics, and provides insights into system usage and performance. Provides visualization and analytics capabilities to monitor system health and user behavior.

## Key Files
- **goals.rs**: Goal tracking and management functionality
- **goals_ui.rs**: UI components for goal visualization
- **insights.rs**: Performance and usage insights generation
- **mod.rs**: Module entry point and exports

## Features
- **Goal Tracking**: Define, track, and visualize goals
- **Performance Analytics**: Monitor system performance metrics
- **User Behavior Insights**: Analyze user interactions and patterns
- **Dashboard UI**: Components for displaying analytics data
- **Visualization**: Charts, graphs, and metrics displays

## Usage Patterns

### Adding a New Goal Type
```rust
// Define goal structure
struct NewGoal {
    name: String,
    target: f64,
    unit: String,
}

// Track goal progress
fn track_goal_progress(goal_id: Uuid, progress: f64) -> Result<(), AnalyticsError> {
    // Implementation
}

// Get goal insights
fn get_goal_insights(goal_id: Uuid) -> Result<GoalInsights, AnalyticsError> {
    // Implementation
}
```

### Generating Insights
```rust
// Get system performance insights
fn get_system_insights() -> Result<SystemInsights, AnalyticsError> {
    // Implementation
}

// Get user behavior analytics
fn get_user_behavior_analytics(user_id: Uuid) -> Result<UserAnalytics, AnalyticsError> {
    // Implementation
}
```

## Integration Points
- Integrates with core system metrics
- Works with dashboard components
- Provides data for visualization
- Connects with user behavior tracking

## Error Handling
Use standard error types from `crate::error` module. All operations should return `Result<T, AnalyticsError>` where AnalyticsError implements proper error sanitization.

## Testing
Tests are located in `tests/` directory with focus on:
- Goal tracking operations
- Insights generation
- Performance metrics calculation
- UI component rendering
