Really nice!

Hi Demian,
absolutely, the error is no bug and correct, Neo4j will require a
slightly different concurrent-client strategy and architecture from
your current setup, but that is no big problem ...

I would need a "neo server" so that multiple applications can run concurrently
using the same data store.
I don't need anything at this moment, since I am only evaluating the software
for my company; I just wanted to make sure the error I saw was "by design".

Hi
I just deployed the peoplemap written by Sasha Agafonoff
http://79.125.12.243/people
Wiki: http://wiki.github.com/sashaagafonoff/peoplemap
It's slow (no optimization anywhere) and buggy.
But it shows what you can do with neo4j and Ruby on Rails and some
flash visualization.

Johan,
My graph has only one type of relationship and it is not hierarchical.
More specifically, it represent an encyclopedia where nodes are the
Pages and arcs are Links from a Page to another Page.

Andrea

Andrea,
Depending on your graph and the traversal you need to perform there
are more memory efficient ways to do it using the core API
(Node.getRelationships* methods).
If you could describe a bit more in detail how your graph looks

I patched the FindSinglePath to support direction. See:

I don't know how hard it would be to add a depth limit to the current
Dijkstra implementation since I didn't implement it myself. The
problem is that by adding a depth limit you will break the algori

Hi Johan,
thank you for your fast reply.
The answer to your question is: Maybe all the nodes of the graph
because (this is what I'm trying to understand), my graph is a great
unique connected component. My traverser is something like:

I'm using JUNG too. Most of their examples are applets, so if that's
within scope it's a possible solution. When looking for toolkits I also
looked at Prefuse and Piccolo2D, but
I think also that the treebolic applet can also input GraphML and maybe
Graphviz dot too, Can't remember the details - but I think you would loose
the ability to lazily load braches.

Hi,
How many nodes do you visit during the traversal?
Currently the traverser implementation makes sure you will not visit
the same node twice and it does this by storing the nodes visited in a
set.

Thanks Anders
However not only is my graph weighted but also I want to traverse only in the
outgoing direction so FindSinglePath does not seem to be appropriate. I can
ignore the weights for now but the direction is really important.
So I need more suggestions. Ideally I would like to somehow ext

HI,
This is my situation, I have a graph with about 7Millions of nodes and
50Millions of arcs.
When I try to traverse the graph (that maybe have a unique connected
component), I always have java heap space problems. Any suggestion
about that?
Thank you in advance,
Andrea

Hi!
If you have an unweighted graph, you could look into using the
FindSinglePath class:

Hello,
I know graphviz, it's possible to output to many formats and graphviz

Hi All
I have a question about the graph algo components of neo4j. Specifically the
org.neo4j.graphalgo.shortestpath.Dijkstra algorithm. Can we limit the search
for shortest path to a maximum degree of depth? For example: if i have a the
maximum degree of depth set to 2 then the following path b

Treebolic looks like an easy option to implement and the graphical rendering
is all client side. It will render graphs as well as trees but needs a focus
node, and can be used in an interactive way.

Others already answered (thanks!), but I'll send this anyhow.

Hi
Sasha Agafonoff uses the Flash Prefuse Flare library in his Rails
peoplemap application for displaying graphs. The neo4j data is
converted to GraphML wich can be loaded very easily into Prefuse
Flare.
Have a look at the result:

You could use Javascript Infoviz toolkit http://thejit.org/.
It accepts data in json format.
