Graphic ontology visualization is important for both ontology technical developers (code writers) and for allowing domain experts to easily evaluate the validity of statements. So, it is mutually beneficial for graphic ontology visualization developers and ontology technical developers to work together in support of one another. One way ontology technical developers could help in this area is to take care  in the design their ontology structure to cleanly breakout separate domains of interest. When the ontology becomes too large for a reasonable graphic representation of the entire ontology, it is likely that a graphical representation of a specific domain of interest could still be of great value to both ontology technical developers and domain experts.

Ø  in others the diagrams get too complicated and isn’t of value. 
Yep – I find that any diagram with more than around 20 resources shown becomes quite hard to deal with. 
In olden times we dealt with this using an A0 plotter. 
These days I think some kind of temporary graph selection is needed. 
General purpose ‘show it all’ solutions are kinda hopeless.

FYI - I developed a JavaScript RDF graph visualiser that runs in a browser using vis.js (a JavaScript port of Graphviz) with a service worker to perform the rendering in the background. I found it easy to customise the rendering via the DOT language. This works well in some cases, but in others the diagrams get too complicated and isn’t of value.

Hi Brent,

tried your tool but can't really make it work...
maybe also have a look at http://vowl.visualdataweb.org/webvowl.html ?

Dear all,

I have been working on a project that loads and visualizes  various
RDF serializations. Right now it is rough, but public:

With D3:

With Sigma.js:

Paste URLs in the text field and press the "Load File/ LDP Container" Button:

Data to play with is here:

h/t to the N3, JSONLD , and the RDFlib libraries.
