* **INTELLIGENCE OPERATIVE PERSPECTIVE**
*
* This dashboard module provides interactive visualization and analysis of Swedish
* Riksdag committee structure, productivity, and decision patterns. Committees are
* where legislative power actually accumulates and policy details get hammered out,
* making committee-level intelligence critical for understanding parliamentary
* dynamics. The dashboard transforms committee data into organizational intelligence
* revealing power distribution, policy priorities, and committee effectiveness.
*
* **STRATEGIC IMPORTANCE OF COMMITTEE ANALYSIS:**
* Swedish parliament operates on a committee-based legislative model where:
* 1. **Committee Pre-Process**: Bills typically go through committee first
* 2. **Committee Bottleneck**: Strong committees can delay/modify legislation
* 3. **Committee Expertise**: Subject-matter expertise concentrated in committees
* 4. **Committee Power**: Committee chairs wield significant influence
* 5. **Committee Compromise**: Coalition deals often negotiated in committees
*
* Committee analysis reveals the legislative power structure beneath the party structure.
*
* **COMMITTEE DEFINITIONS (15 Swedish Committees):**
* Dashboard tracks all major Riksdag committees with specialized domains:
*
* **Security & Foreign Policy:**
* - AU (Utrikesutskottet): Foreign Affairs Committee
* - FöU (Försvarsutskottet): Defense Committee
* - KU (Konstitutionsutskottet): Constitutional Committee
*
* **Economic & Fiscal:**
* - FiU (Finansutskottet): Finance Committee (budget authority)
* - NU (Näringsutskottet): Industry Committee
* - TU (Trafikutskottet): Transport Committee
*
* **Social Policy:**
* - SoU (Socialutskottet): Social Affairs Committee
* - MU (Miljöutskottet): Environment Committee
* - KrU (Kulturutskottet): Cultural Affairs Committee
*
* **Justice & Administration:**
* - JuU (Justitieutskottet): Justice Committee
* - CU (Civilutskottet): Civil Affairs Committee
*
* **Health & Education:**
* - HsU (Hälso- och sjukvårdsutskottet): Health & Welfare Committee
* - UU (Utbildningsutskottet): Education Committee
*
* **Other:**
* - EU-nämnden: EU Affairs Committee
* - StU (Statsutskottet): State Committee
*
* Each committee configured with:
* - Swedish abbreviation (AU, FiU, etc.)
* - English and Swedish full names
* - Color coding for visual distinction
* - Policy domain classification
*
* **ANALYTICAL DASHBOARDS:**
* The dashboard provides four intelligence views:
*
* 1. **Committee Network Diagram (D3.js Force-Directed Graph)**
* Visualizes: Committee relationships and information flow
* Algorithm: Force-directed layout shows proximity = collaboration
* Intelligence value: Identifies committee clusters and power hubs
* Use case: Find interconnected committee structures
*
* 2. **Productivity Heat Map (D3.js Heatmap)**
* Visualizes: Committee activity and productivity over time
* Metrics: Document production, meeting frequency, decision rate
* Intelligence value: Identifies busy vs. dormant committees
* Use case: Track committee workload and priorities
*
* 3. **Voting Pattern Analysis (Chart.js Multiple Charts)**
* Visualizes: Committee decision patterns and unanimity rates
* Metrics: Agreement rates, dissent frequency, consensus strength
* Intelligence value: Committee consensus/conflict assessment
* Use case: Identify contentious policy areas
*
* 4. **Seasonal Activity Patterns (Chart.js Line Chart)**
* Visualizes: Committee activity variation by season
* Metrics: Meeting frequency, document volume by month
* Intelligence value: Budget cycle and legislative timing
* Use case: Predict when committees will be active
*
* **DATA SOURCES:**
* CIA Platform provides committee intelligence:
* - distribution_committee_productivity_matrix.csv
* Committee productivity metrics and activity levels
* - view_riksdagen_committee_decisions.csv
* Committee voting records and decision patterns
* - distribution_annual_committee_documents.csv
* Document production by committee and year
* - view_riksdagen_committee_ballot_decision_party_summary.csv
* Party-specific voting patterns within committees
* - percentile_seasonal_activity_patterns.csv
* Seasonal variations in committee activity
*
* **CACHING STRATEGY:**
* Dashboard implements efficient multi-level caching:
* - **Browser Cache**: 24-hour local storage
* - **Data Sources**: Local files first, GitHub fallback
* - **Automatic Refresh**: Stale cache invalidated after 24h
* - **Cache Key Prefix**: riksdag_committee_ (avoids conflicts)
* - **Parallel Loading**: Multiple sources loaded simultaneously
*
* **INTELLIGENCE APPLICATIONS:**
* 1. **Power Distribution**: Identify which committees wield most influence
* 2. **Productivity Analysis**: Track committee effectiveness over time
* 3. **Coalition Control**: Assess coalition's hold on key committees
* 4. **Policy Priority Detection**: Identify committees getting resources
* 5. **Committee Conflicts**: Track contentious committee decisions
* 6. **Member Influence**: Identify powerful committee chairs/members
* 7. **Timeline Prediction**: Predict when committee actions occur
*
* **PARTY CONTROL ANALYSIS:**
* Dashboard tracks party composition of committees:
* - Committee chair parties (indicates committee control)
* - Party representation by committee
* - Coalition vs. opposition committee balance
* - Coalition's control of key committees (Finance, Justice, Defense)
*
* **PERFORMANCE METRICS:**
* Dashboard calculates committee-level KPIs:
* - **Productivity Index**: Documents produced per meeting
* - **Decision Frequency**: Decisions per unit time
* - **Meeting Frequency**: Regular schedule compliance
* - **Unanimity Rate**: Percentage of unanimous decisions
* - **Dissent Frequency**: Cross-party voting patterns
*
* **ACCESSIBILITY FEATURES:**
* WCAG 2.1 AA compliance:
* - Color-blind friendly palette
* - Text labels on all visualizations
* - Keyboard navigation support
* - ARIA labels for screen readers
* - High contrast mode
* - Responsive design (320px-1440px+)
*
* **MULTILINGUAL SUPPORT (14 Languages):**
* Complete internationalization:
* - Swedish: Detailed terminology
* - English: International audience
* - Nordic: Regional users
* - European: Continental coverage
* - Middle Eastern: Diplomatic audience
* - Asian: Economic representation
*
* Committee names and explanations translated appropriately.
*
* **RESPONSIVE DESIGN:**
* Dashboard adapts to all screen sizes:
* - **Mobile (320px)**: Stacked layout, single chart per view
* - **Tablet (768px)**: Two-column layout, selectable views
* - **Desktop (1920px)**: Four-chart dashboard, detailed annotations
* - **UltraHD (2560px)**: Detailed network graphs with zoom capability
*
* **FAILURE HANDLING:**
* Graceful degradation:
* - Local Cache Hit: Use cached data (24h TTL)
* - Remote Fallback: GitHub data if local unavailable
* - Error Display: "Data unavailable" vs. breaking UI
* - Retry Logic: Automatic retry on network failures
* - Partial Data: Display available data even if incomplete
*
* **GDPR COMPLIANCE:**
* Committee data handling (public parliamentary records):
* - Committee member names published (public roles)
* - Voting records public (parliamentary transparency)
* - Aggregation respects privacy (committee-level, not member-level)
* - Data retention follows parliamentary archive standards
*
* **SECURITY CONSIDERATIONS:**
* Data integrity and authenticity:
* - Data Validation: Checksums verify source data
* - Timestamp Validation: Ensures data freshness
* - Source Verification: CIA platform authentication
* - Anomaly Detection: Unusual data patterns trigger review
* - Access Control: Committee analysis logged for audit
*
* @osint Organizational Intelligence Analysis
* - Maps committee power distribution
* - Tracks policy prioritization through committee resources
* - Identifies policy bottlenecks in specific committees
* - Analyzes coalition control of critical committees
*
* @risk Governance Structure Assessment
* - Committee effectiveness indicates government functioning
* - Productivity trends show policy momentum
* - Coalition control of committees affects policy implementation
* - Committee conflicts indicate policy disputes
*
* @gdpr Public Committee Records
* - Committee decisions are public
* - Member participation public (published records)
* - Aggregation protects individual privacy
* - Retention follows parliamentary archive standards
*
* @security Committee Data Integrity
* - Data sourced from official CIA platform
* - Timestamps prevent tampering
* - Checksums validate authenticity
* - Anomaly detection identifies corruption
