Alfredas,
thanks for pointing that out. What documentation are you referring to? The
reference docs of spring-data-graph or the neo4j wiki?
Several people documented that independently and I still have to catch up
updating all those places.
I assume you got the samples from github?
We want
Alfredas,

yes, spatial visualization based on OpenLayers and Neo4j Spatial would
be something, at least as one possible layout algo that you could plug
in. How are you thinking around arbitrary non-spatial info? Not sure
how good the layout performance of OpenLayers is.

Hi!
Looks like one of the Hudson bugs that hit the buildbox randomly. I
started a new build, and it was fine this time.
For some reason archiving of sites is prone to trigger different bugs in
Hudson. (I don't remember seeing this specific one previously.)

Sorry Peter, misread you. What I was thinking was to render non-spatial
graphs with neo4j spatial. A layout algorithm would calculate the
coordinates of each node we want to visualize. That way we can view really
big graphs in the browser, since the layout-work is already done by the
server.
Den
Intriguing option. So you assign virtual locations based on the layouting
algorithm, and then use neo4j-spatial's 'export to PNG' capabilities, which
also makes use of SLD for styling (geoserver-like styling, using geotools
inside, of course). This is certainly not an option I had every
Mhh,
interesting! I wonder if there is any support for using e.g. GeoTools
to render arbitrary layouts apart from spatial. Would be worth to
investigate. The nice thing is that these algos support, as you
mention, zomming into a static structure, and espose more and more
detail on every layer.
Yep. I slippy graph like google maps - with details an different zoom levels!
Awesome!

In this case, the graph layout could be computed server side by
something like graphviz or so, and then sliced into zoom level
information. Then interactivity can be added via open layers .
However, of course the question is how long it takes to calculate the
layout for say 100.000 nodes. After
Tied in with my SVG question (which should be posted shortly), you can move
some of the UI rendering to the server as well, and with SVG you could
cleanly integrate data + UI elements in what is sent back to the browser. I
think a mix of browser smarts to control client-side rendering (zoom
Out of curiosity, has anyone looked at re-doing the rendering engine of this

for web apps is much more substantial. Issues like hit testing/item

I think a mix of the two approaches, as Rick says, handling the
selection of detail to stream via some zooming logic interactivity via
SVG/JavaScript on the client is a good approach.
The other is the selection of only a subset via a traversal and not

Using a pre-made layout solution would indeed be optimal, no reason to
re-invent wheels. Apart from the layout, we'd get the rest for free from
neo4j spatial and surrounding technologies.
This would be a separate visualization tool, with an ability to let clients
explore massive graphs via a

Already did, and they seem to get lost right before the Neo4j network. But
traceroutes can lie. Anyway, checked with other US people, they can access
it fine, so it's probably just my local network/computer at home that's
screwy somehow.
