What's an Idea for a Beginner Project that involves TDA?

I am an undergraduate in math just beginning in data science looking for ideas to do a data science project that involves Topological Data Analysis. I've been reading privately on algebraic topology, and I think it would be really neat to apply some of these ideas to my future data science career. any ideas you have would be great. Please keep in mid that I am very new at this, and I only know Python, R, and am currently learning the DS packages for Python. Thank you.
