add example visualizations

[VladimirAlexiev]

The first thing one wants to see before trying to build/install a visualization tool is ... some visualizations.

So please add some for a quick view, even in the README (home page).

I found some eg here, are they representative?

• https://github.com/ahmad88me/IEBrain/blob/master/OnToology/iebrain-actor.owl/diagrams/ar2dtool-taxonomy/iebrain-actor.owl.png

There's a better example at https://twitter.com/ar2dtool/header_photo, is it produced by the tool without "doctoring"?

Thanks for the suggestion. I think these are relevant enough, so I will add them to the README. @ahmad88me ¿any issues using the linked images?

@idafensp What is a linked image 😅 ?

I meant the two images linked in the original comment:

https://github.com/ahmad88me/IEBrain/blob/master/OnToology/iebrain-actor.owl/diagrams/ar2dtool-class/iebrain-actor.owl.png
https://github.com/ahmad88me/IEBrain/blob/master/OnToology/iebrain-actor.owl/diagrams/ar2dtool-taxonomy/iebrain-actor.owl.png

Both belong to your IEBrain project.

The only issue that I remember is the pixilated images for large ontologies. Probably this can be solved using svg.
