Hi,

This is pretty good stuff. Do you happen the link to download the source? It looks like download for source is broken.

Thanks a lot.

Thanks for the response. I commented out those lines, and sure enough it worked perfectly.

I actually created a new edge renderer that adds a arrow head to the end of the edge, and was testing it out in your sparql viewer.

THanks for the help.

Jay,

Yes. I had to comment out the lines at about line 1480:

/*
if(_componentCounter > (_noVisibleVNodes)) {
throw Error(”Got too many components:”+_componentCounter+” but only:”+_noVisibleVNodes
+” nodes visible”);
}
*/

I was getting the same error. I think these are just debug statements. If you pick up the libs from this source distribution then you will have this change built in. Better still the libs for the social graph browser have the fix for the drag-end not being detected as well. Have a look at the graph forum for posts by me ‘www.netthreads.co.uk’. I should maybe have pointed this out (slips away slopy shouldered)

Did you use a custom build of the flexvizgraphlib for this project? I’m using the latest flexvizgraphlib from svn, and an getting this error:

Error: Got too many components:2 but only:1 nodes visible
at org.un.flex.graphLayout.visual::VisualGraph/createVNodeComponent()[C:\flexvizgraphlib-read-only_NEW\graphLayout\org\un\flex\graphLayout\visual\VisualGraph.as:1480]

but then it renders fine

Thanks for the help.

Hello! It looks really nice
I tried it with the Jamendo end-point at http://dbtune.org:2105/sparql/ but no luck: it seems to hang (it works fine with other sparql clients).
Cheers, and many thanks!

Nice tool!
Can you not process SPARQL DESCRIBE and CONSTRUCT Queries?

Thank you for posting this. I have a simple graph of companies I loaded into another viz tool that I’d like to port over to Sparql, your notes are good although to the uninitiated they get us excited but need to figure out how to format input file to display on screen. Will check it out and see what it takes.
