Is there any dataset with trees or acyclic graphs available?

I am working on a structured data analysis (for clustering and classification) algorithm and I am looking for a dataset to test it. Could anyone let me know if there is any dataset that contains trees or acyclic graphs available? It would be great even if they are synthetic.

Here is some data from a course project for predicting optimal loop unroll amounts in gcc, modelled after a study by Leather et al (see attached pdf). Loops have a natural hierarchical tree representation.

The data was intended to be parsed with python, and you'll probably want to read the attached README first. Let me know if you have questions.
