No module named PyQt5.QtDataVisualization

To resolve the error "No module named PyQt5.QtDataVisualization," you need to install the PyQt5 library along with its QtDataVisualization module. You can do this by running the following command in your terminal:

pip install PyQt5

If you have already installed PyQt5 but are still encountering the error, you may need to install the additional module separately. You can do this by running:

pip install PyQt5.QtDataVisualization

Make sure you have the correct version of PyQt5 installed for your Python environment, and if necessary, update it using the command `pip install --upgrade PyQt5`.
