The first two shapes on the left look like chemical structures for oxygen and cyclic ozone, but the third... maybe a messed-up carbon tetraoxide (in D2d configuration) with missing interoxygen bonds? Or maybe the whole thing is just coincidence (when drawing circles connected by lines)?

It's the exact same symbols present in her official art, just missing the additional horizontal lines. Couldn't say if ZUN had specific ideas of what they represented.
