I typically just list things I've worked with, no matter the experience level. I like to do so because then the interviewer has to ask about them in an interview, where I'd then get a chance to (subtly) showcase my knowledge and enthusiasm. From my own anecdote: I had an interviewer ask me about something I had listed in my resume (but not related to the job position). It made for good conversation and allowed them insight that they otherwise wouldn't have seen with a straight technical question. Edit: Hopefully I didn't go off topic with my comment, but I also think the graphic indicator was a clever and very straightforward way of expressing experience level. It just doesn't seem very space efficient if on a paper resume.
