Regarding visualisation of Linked Data, it should be avoided to fall victim to what was called "the pathetic fallacy of RDF" in one publication [1], i.e., visualising RDF data as graphs because the underlying datamodel is a graph, not because the use-case at hand requires this kind of visualisation (many do not).

[1] http://eprints.ecs.soton.ac.uk/12911/1/the_pathetic_fallacy_of_rdf-33.html

I have not found many _generic_ RDF visualisations that would even be remotely useful to end-users. However, if tailored/specialised SPARQL queries are needed to distil the data for visualisation, I wonder if visualisation of data from Linked Data sources is so much different from visualizing other kinds of complex data (?)

Hi all,  

During the telco today Eric mentioned  http://www.distilbio.com/ , which was apparently built on top of exhibit3, seems like a great way to start.

I would propose not to limit ourselves to "ways to visualize RDF graphs", but to actually try to plug linked data into data visualization paradigms already widely adopted, like dendrograms, heatmaps, sunburst plots, etc

Example of a heatmap built from a SPARQL query (medicines VS their classes):


Finally, in the same lime of thinking,  a TED talk by Jer Thorp (NYT) about visualization -http://www.youtube.com/watch?feature=player_embedded&v=Q9wcvFkWpsM

There's lots of really REALLY cool js libraries that we could use for very quickly prototyping!

  A task force on visualization is a great idea.  And it would make sense to have it aimed at and work with helping each of the other task forces utilize visualization capabilities.  It's something I've been thinking about with respect to the work we did on the TMO/TMKB. How do we demonstrate beyond sparql queries?

Please reply indicating your interest.
