It's not about graph visualization. It's about user interaction for
graph-based data.
Georgi,
Is this an apropos or an insight addition?
My entire position about Linked Data solutions is centered on "User
Interaction". Note, I said: "Visualizations are good, but graph
visualizations are not the sole keys to the treasures that reside within
a Graph".
I regard "Data Access" as part of "User Interaction". This is why the
OpenLink Data Explorer extension (for instance) simply adds the ability
to "View | Linked Data Sources" to its host browser. All it is really
doing is providing the user with a route to a beachead from which a
query could be beamed (i.e. SPARQL + Full Text under the covers across
the data sources in it's history).
Give users the "option" to use their own cognitive skills to interact
with the data (e.g. pivot, project, and traverse based on their own
specific needs).
We are repeating a long history of not understanding intersection of
"User Interaction" and "User Cognitive Skills" if we don't provide
routes to the data behind subject projections. This matter has been the
same since advent of the IT era:
1. Executive Information Systems (what used to be called EIS)
2. Report Writing Systems (Cognos, Crystal Repors, Business Objects,
Brio, Forest & Trees, I can go on, used and worked with all of them)
3. Dektop Productivity Tools (Access, MS Query, Paradox, and many more)
"User Interaction" is a about a rich set of options that provide outlets
for cognitive prowess. Programmers cannot acquire the domain expertise
of an alien domain.
BTW - I also gave an "User Interaction & Linked Data" talk / demo [2] at
the most recent Cambridge Semantic Web Gathering.

How is your knowledge base structured? What language?
Can I download your program to my computer?

David,
For purpose of clarity and broader discourse (I know we've been over
this in private), what is the Linked Data and/or Semantic Web oriented
value of this very cool visualization?
Put differently, it would be nice if I could beam a query down the
data
graph exposed by you very nice visualization rather than being
confined
to the options presented by your application.
At the very least, what's the harm in exposing the Freebase URLs in
these Web Pages? If you do that, at the very least, other user agents
can do stuff with the graphs (Linked Data) that you are visualizing.
The cost of this little tweak is extremely low and the upside
extremely
high.
Cool stuff for sure, but I would like Parallax to be a nice Linked
Data
Web contribution also :-) Freebase (basic) is part of the Web, but
Parallax is sort of confining me to a Freebase enclave by not exposing
URLs (where I currently see: javascript:{}).
My fundamental argument remains this:
Visualizations are good, but graph visualizations are not the sole
keys
to the treasures that reside within a Graph. Effective traversal (e.g.
query beaming SPARQL or MQL) is also part of the puzzle, and it would
be
nice if we could always offer the visualization and the
graph-query-beam-beachhead as part of a single Web information
resource
deliverable. There are always reasons why one or more humans (due
inherent cognitive prowess) would seek to view the same data
differently, no matter how compelling the initial visualization, due
to
the fact that data visualizations are inherently subjective
projections.

Freebase ( I get no triples with Parallax pages since the Freebase
Data
Sources aren't exposed)
Note: The Freebase RDFization Cartridge (Wrapper, Scrapper etc.) will
be
better i.e., right now there are too many literal property values that
should be URIs (this fix is coming). Ditto proper lookup driven
meshing
with DBpedia.

Subject: freebase parallax: user interface for browsing graphs of
data
Hi all,
I've been exploring some user interface ideas for browsing graphs
(of
data in Freebase) in a user-friendly way, which I think might be
applicable to some of the data that you have. The screencast should
explain:

Please let me know what you think!
Thank you.
