16 out of 21 tests failed

[zxytim]

I intended to submit a pull request on bug fixes, however, the existing tests are largely broken.

I just clone the main branch of termgraph (to be exact, commit 63491d8), and run pytest tests. It outputs a bunch of errors, showing test statistics at the end:

================ 16 failed, 21 passed in 0.63s ==================

Could you please fix these tests? @mkaz

@zxytim I fixed and removed some tests in #72. Hopefully that helps, once that's merged in!

I'm fairly sure this issue can be closed now. I checked out e8c211b and all 20 tests passed.
