 ### Key Components
 
 **Data Layer:**
+
 - `data/parser.py` - NDJSON parsing with error handling
 - `data/processor.py` - Data transformation and combination logic
 - `models/schemas.py` - Dataclasses for type safety and validation
 
 **Algorithm Layer:**
+
 - `models/reducers.py` - Modular dimensionality reduction with factory pattern
 - Supports PCA, t-SNE (openTSNE), and UMAP algorithms
 - Abstract base class for easy extension
 
 **Visualization Layer:**
+
 - `visualization/plots.py` - Plot factory with single and dual plot support
 - `visualization/colors.py` - Color mapping and grayscale conversion utilities
 - Plotly-based 2D/3D scatter plots with interactive features
 
 **UI Layer:**
+
 - `ui/layout.py` - Main application layout composition
 - `ui/components/` - Reusable, testable UI components
 - `ui/callbacks/` - Organized callbacks grouped by functionality
 - Bootstrap-styled sidebar with controls and large visualization area
 
 **Configuration:**
+
 - `config/settings.py` - Centralized settings with environment variable support
 - Plot styling, marker configurations, and app-wide constants
