Hello Codeforces community,

I'm presenting to you two tools tool that I have created that may help you debug graph problems.

The first one is a graph drawing tool, where you can draw the graph and then generate its test case, this may be helpful when you need to write your own test cases for your graph problems, and need to easily visualize and edit them.

The second one is a random test case generator, where you can generate huge test cases according to certain conditions (like weighted vs unweighted, directed vs undirected..etc).

Feedback is appreciated.

Thank you.
