I was thinking about tooltips but those are tricky to implement for mobile devices (although I haven't spend much time making it usable for small screens/devices)

I am not sure if you had a look at the "pentanizer" parts, but that one is even worse at first sight, but once you isolate certain parts I think (very subjective) it becomes helpful if you study interval parts.
There is a youtube link video link included which explains the concept.
