Challenge 1 Feedback: 8/20
Overall: Code is generally good, need to improve file reading and add more error handling.

• Solution 2

• sample 3 file has an edge to a vertex not in the vertex list - your code should either error on this or add the vertex in - yours does neither.

• Documentation 3

• Looks good - consider adding parameters and runtime to docstrings.

• Code Organization 2

• Need to separate file reading from graph creation - these should not be coupled.

• Testing 1

• A few tests but not error handling

from cs-2-2.
