Data Visualization App (Prototype) This is a minimal, well-structured PyQt5 prototype for your final year project. It supports:

• Loading CSV/Excel files
• Previewing dataset (first few rows) in the GUI
• Creating basic plots: bar, line, histogram, pie
• Exporting charts to PNG and PDF
• Saving/loading chart configuration (JSON)

How to run (basic):

1. Create a virtual environment (recommended) python -m venv venv source venv/bin/activate # Linux/macOS venv\Scripts\activate # Windows

2. Install requirements: pip install -r requirements.txt

3. Run the app: python main.py

Files: main.py - app entrypoint core/ - backend modules (data loader, chart generator, export, config) gui/ - PyQt5 UI modules (main window, chart view, controls) sample_data.csv - small sample dataset you can use immediately

Notes:

• This is a prototype with educational, modular code. Each module has clear responsibilities.
• Use VSCode to open the folder and explore modules. Run main.py to launch the GUI.
