Hi Hebert, in addition to my previous reply (quoted below in case it's of an interest to the Forum),

Further information is there in the README file - please ask me if you've never used Jupyter before. Note also that the notebook will not be preserved after the browse window is closed, but you will be able to download the notebook in various formats by going to "File" -> "Download as" in the Jupyter menu. If you need to use Digraphs only from time to time, that may be a suitable way to get it working remotely without installing Cygwin.
