Say you have the following data:

From, To, Amount
123, 456, $10000
123, 789, $10000
456, 369, $10000
789, 369, $10000
369, 258, $20000
258, 123, $20000
147, 369, $30000
789, 147, $50000

The data shows transactions flowing between accounts, but it's hard to "see." That was the question posed by Michelle Lam - how can we generate network visualization with/from Lavastorm?

Adrian Williams realized that of the many available options, one easy one is the R-package called 'igraph'. Here's a nice description of it:

So here's an example of how we can leverage the R node in Lavastorm. For more information on setting up R, see this link (right hand side).

Thanks for posting this, Roger. This is related to the other thread that I just posted to ask whether anyone has used Lavastorm to produce a graphML output:
http://community.lavastorm.com/threa...graphML-format

I understand that there are other products geared for this type of network visualisation that are compatible with graphML file format so being able to produce a file of this format would also open other potential options, both licensed and open source.

If you don't already have the igraph package installed then you will need to do this first, within the R Console type the following command: -

install.packages("igraph")

Select an appropriate download mirror and the package will install. The R script in Roger's excellent graph may point to different location so I have updated the graph to include a parameter for both nodes to use. My library installed to C:/Program Files/R/R-3.1.1/library.
