You need at least python 3.8+ (a lot of walruses :=).
You need to have make and python installed, e.g.:
apt/yum install make
The init target in Makefile creates, activates and installs requirements to a virtual environment.
make init
The main entry point is app.py, you can run the app either by:
make run
or
python3 app.py
or
chmod +x app.py
./app.py
Then head to localhost:8050
make clean
