As I have read here there was an option to configure your own style:
I can still take a look at my style but I cannot define it at the beginning. Is it even possible to specify that e.g. all company nodes are red, all employee nodes with a certain property are green? ...
or what have you, along with modifying any of the other options shown in that :style snippet you shared. I don't believe it is possible to define styles based on a certain property, just based on labels (or relationship type).
