Visualize Indiviuals #193
Description
Is your feature request related to a problem? Please describe.
Currently, individuals are not supported in the visualization. This is a pain point for some users of WebVOWL.
Describe the solution you'd like
Being able to visualize individuals as nodes with edges similar to e.g. "owl:Class".
Additional context
Note that we must also be able to filter/hide individuals, as some users are not interested in seeing them.
