// Dashboard Renderer - Chart and Graph Rendering Engine
//
// This module provides advanced rendering capabilities for dashboards:
// - Real-time chart rendering (line, bar, pie, heatmap)
// - Topology and dependency graph visualization
// - Template engine for dynamic content
// - WebSocket-based live updates
