I realize what I want to do is launch Glue (from Python) and then in Glue click on "Open Session" to open a previously saved session with desired the charts already set up. As long as I have replaced the source data file with an updated one from Python, my Glue session will now display the latest data in the format I want. My programming level is not good enough to write my own Pickle file loader, and a Numpy file will lose the column titles, so I'll stick with CSV files for now.
Is it possible to launch Glue with a previously saved session, directly from Python?
