# Documentation: DTS.Viewer Main View Components

## 1. Purpose

This module contains the main view components for the DTS Viewer application, implementing a WPF-based visualization and export system. It provides multiple view variants (standard, lite, export, and viewer modes) that serve as UI shells for chart/graph visualization and PDF export functionality. The views follow a code-behind pattern with XAML partial classes, integrating with Prism's event aggregation system for loosely-coupled communication between components.
