This code was partially borrowed from mwhittaker and extrapolated for my personal use. You can record your squat, bench, deadlift and weight by command-lining the following:
python3 logger.py bench 225
If you would like to view the graph visualization of that particular lift over time:
python3 logger.py bench 225 open
which will open up an interactive graph in your default browser.
Otherwise, if you would just like to view a particular graph without actually logging a new entry:
python3 logger.py bench javascript
Hope you enjoy!
