annotation is shown correctly
but the annotation in owl is to be completed in protege
arc and arrow positions are fixed.

unshownchildrenCount label location is fixed
seems everything is finally done?

color, stroke, arrow .. fixed
layout size fixed before runLayout, finally, gosh
rotation fixed
finally understand the update and set method of node, so easy but I didn't notice ever before. Waste a lot of time.

only the ontology itself is not complete
