# Personal AI Infrastructure — Data Visualization Module

**Version**: v1.2.3 | **Status**: Active | **Last Updated**: March 2026

## Overview

The Data Visualization module provides charting, dashboards, and visual reporting for code metrics, performance data, and analytics. It generates interactive charts and static visualizations for agent-produced data.

## PAI Capabilities

- Chart generation (bar, line, scatter, heatmap)
- Dashboard composition with multiple chart panels
- Performance regression visualization
- Metric trend analysis and alerting visuals
- Export to PNG, SVG, and interactive HTML

## Key Exports

| Export | Type | Purpose |
|--------|------|---------|
| Chart generators | Various | Create charts from data |
| Dashboard builders | Various | Compose multi-panel dashboards |

## PAI Algorithm Phase Mapping

| Phase | Data Visualization Contribution |
|-------|----------------------------------|
| **OBSERVE** | Visualize codebase metrics for understanding |
| **VERIFY** | Chart performance benchmark results for regression detection |
| **LEARN** | Generate trend visualizations for long-term tracking |

## MCP Integration

Charting and dashboard tools available for PAI agent consumption.

## Architecture Role

**Core Layer** — Consumed by `performance/` (benchmark visualization), `maintenance/` (health dashboards), and the PAI dashboard.
