How to verify Matplotlib installation?

To verify your Matplotlib installation, follow these steps:

1. Open a Python Environment:

   • You can use a terminal, command prompt, or an IDE like Jupyter Notebook or PyCharm.

2. Import Matplotlib:

   • Run the following command:

     import matplotlib

3. Check the Version:

   • To confirm that Matplotlib is installed and check its version, run:

     print(matplotlib.__version__)

4. Test a Simple Plot:

   • You can create a simple plot to ensure Matplotlib is functioning correctly:

     import matplotlib.pyplot as plt
     
     plt.plot([1, 2, 3], [4, 5, 6])
     plt.title('Test Plot')
     plt.show()

If you see the version number printed and a plot window appears, Matplotlib is installed and working correctly. If you encounter any errors, you may need to install or reinstall Matplotlib using:

pip install matplotlib
