Closes #522

Description

This pull request introduces a comprehensive data visualization layer across the frontend application using Recharts. It establishes a reusable chart component library that integrates seamlessly with the existing design tokens and theming engine, ensuring support for both light and dark modes.

The implementation delivers robust analytics capabilities for player statistics, platform dashboards, and tournament results while adhering strictly to accessibility (WCAG AA) and performance optimization standards.


Changes Implemented

1. Architecture & Component Foundation

  • Installed and configured Recharts as the primary charting utility.
  • Created a reusable ChartContainer wrapper to handle responsive scaling, centralized tooltip styling, and consistent legend positioning.
  • Integrated application design tokens for dynamic color mapping (grid lines, text, fills, and strokes) across themes.

2. Feature Implementation

  • Player Stats: Added charts tracking player performance metrics over time, including win/loss ratios and progression data.
  • Analytics Dashboard: Implemented an aggregate dashboard view utilizing mixed chart types to display complex platform metrics.
  • Tournament Results: Developed distribution and progression charts to visualize tournament placements and outcomes.

3. Optimization & Accessibility

  • Leveraged code-splitting and lazy loading for chart modules to minimize the initial bundle size.
  • Implemented proper ARIA attributes, semantic fallback descriptions, and high-contrast color palettes to meet accessibility standards.
  • Optimized rendering paths to eliminate layout shifts during theme toggling and data updates.

4. Testing & Documentation

  • Added unit tests verifying chart rendering, data parsing logic, and responsive behavior.
  • Provided inline documentation and TypeScript definitions for all new chart components.

Verification and Testing

Automated Tests

  • Executed unit tests for core chart rendering components.
  • Validated TypeScript compilation and linting rules.

Manual Verification

  • Verified interactive features including tooltips, hover states, and filter transitions.
  • Confirmed theme consistency by toggling between light and dark modes.
  • Checked color contrast ratios to ensure compliance with WCAG AA guidelines.

The matchmaking_queue.status column is typed INTEGER (0=waiting, 1=matched,
2=expired, 3=cancelled). The partial index WHERE clauses were using string
literals ('waiting', 'matched') which PostgreSQL rejects with:
  invalid input syntax for type integer: "waiting"

Replace with the correct integer constants:
  WHERE status = 'waiting'  ->  WHERE status = 0
  WHERE status = 'matched'  ->  WHERE status = 1

Fixes CI job 83491909707 / migration 20260601000001.
