The heatmap displays stock performance with box sizes representing market capitalization and colors indicating percentage changes.\n\n## Features\n\n- Real-time data fetching from Yahoo Finance\n- Interactive treemap heatmap visualization\n- Box sizes based on market capitalization\n- Color coding based on stock price percentage change\n- Responsive design for various screen sizes\n- Tooltip with detailed stock information\n\n## Installation\n\n1. Clone the repository:\n   ```\n   git clone https://github.com/marketcalls/highcharts-heatmap.git\n   cd highcharts-heatmap\n   ```\n\n2. Create a virtual environment and activate it:\n   ```\n   python -m venv venv\n   source venv/bin/activate  # On Windows use `venv\\Scripts\\activate`\n   ```\n\n3. Install the required packages:\n   ```\n   pip install -r requirements.txt\n   ```\n\n4. Ensure you have a `symbols.csv` file in the root directory with the Nifty 50 stock symbols.\n\n## Usage\n\n1. Run the Flask application:\n   ```\n   python app.py\n   ```\n\n2. Open a web browser and navigate to `http://localhost:5000`\n\n3. The heatmap will load, displaying the Nifty 50 stocks. Hover over boxes for more details.\n\n## Configuration\n\n- Modify `symbols.csv` to change the list of stocks displayed.\n- Adjust the color scheme in `index.html` by modifying the `colorStops` array.\n- Customize the data fetching interval in `app.py` by changing the `timedelta` value.\n\n## Contributing\n\nContributions are welcome!
