/**
 * Test script to verify the Keyword Trend Analysis Implementation
 * 
 * This script validates that the implementation meets the acceptance criteria from Story 1.2:
 * 1. Users can enter keywords and see frequency analysis (daily, weekly, monthly, etc.)
 * 2. The analysis is displayed in a clear, understandable format
 * 3. The feature integrates with the existing source management workflow
 * 4. Results are returned within 3 seconds for typical queries
 * 5. The button initially displays "Analyze" to trigger keyword analysis
 * 6. After analysis completion, the button maintains its "Analyze" state
 * 7. The button state persists correctly through UI interactions
