Cheng Li created a graph of the precipitation and river flow rate in a Jupyter Notebook, similar to
Neal Jander's flow rate Shiny App.
Additionally, I've created a Jupyter Notebook for exploring the TDML measurements from CEDEN. This notebook will give you some insight in to the structure of the dataset and how to use it, since I have found good documentation.
For Cheng's notebook, you'll need to download the data first; look for the links for "Precipitation" and "Flow Rate". On the TGML notebook, the data is loaded from our data repository, so you can download the notebook and run it immediately.
