# Introduction Sankey diagrams are flow diagrams that show the movement of resources or energy between different stages or systems. In this tutorial, we will use the Matplotlib library in Python to create Sankey diagrams. ## VM Tips After the VM startup is done, click the top left corner to switch to the **Notebook** tab to access Jupyter Notebook for practice. Sometimes, you may need to wait a few seconds for Jupyter Notebook to finish loading. The validation of operations cannot be automated because of limitations in Jupyter Notebook. If you face issues during learning, feel free to ask Labby. Provide feedback after the session, and we will promptly resolve the problem for you.
