Re: ANN: Spark library for visualizing the Semantic Web (dev preview)

Hi Denny,

that looks cool! I noticed the "reduced" functionality, and the "TODO"
you have in the source code for the reducer. It seems you might have
use of a utility I've made called SparqlTree [1]. It makes trees out
of sparql results (instead of using the flat "join tables" directly).
There is a JS implementation [2], along with a simple example at [3].

I hope you'll find it useful for richer result data (e.g. where there
are multiple values for some properties per subject, more than one
step along a relation, etc).

Best regards,
Niklas
