How to Visualize Graph Of Hierarchy/Tree Structure?

[Rodger]

Dear Experts,

I'm going to put some hierarchy/tree structure data into NEO4J. 

There will be dozens, perhaps hundreds of branches and leaves.  

All coming back to a few starting nodes (roots). 

What would be the best software (or method, algorithm, etc.) to visualize it?

So that the few roots start at either the bottom or the top. 

Thanks a lot!

Best, 

Rodger

Good question, depends on your use-case, usually you can just show a part of the tree and then drill down.

D3 has a number of examples on how to represent drill-down trees in graphs: https://github.com/mbostock/d3/wiki/Gallery

In general most graph vizualizations are quite use-case dependent, so if you could tell a bit more about your use-case it would help find a suitable visualization.

HI Michael, 

Thanks for responding. 

Something like a family tree. It's just an initial project.

As I've said in my blog, graph db represents tree 

structures much better than RDBMS. 

From the examples you mentioned, these types would work:

d3.layout.tree

Cool interactiveness with this one!

Pedigree Tree

Although I was thinking of having the key root node at the bottom,

like this one:

Binary tree implemented using D3

So you're thinking of D3 as the visualization tool then?

How about in Gephi?  Which style/format would work?

Thanks!
