On pypi, the ppgplot cannot be downloaded: https://pypi.org/project/ppgplot/1.3/
So stvid/extract.py cannot be used as expected.
I noticed there's another version of ppgplot: https://github.com/trmrsh/ppgplot
Can this third-party modified ppgplot fit into stvid?
If not, what else solution is there?
Thank you!
