Plotting a 30M row data frame causes memory only to increase. Also memory isn't collected by gc.collect.
As discussed with matplotlib guys in matplotlib/matplotlib#21259 (and Jupyter guys: jupyterlab/jupyterlab#11182) - we tested and it works as intended. I tested further and think I found the issue - %matplotlib widget:
