Objective
To explore the ONSC data visually as a graph using Gephi

Proceedure
The [|ONSC data] was downloaded from the real-time Googel Spreadsheet December 17, 2010. The data was then split into two files, [|nodes] and [|edges], in preperation for importing into Gephi. An [|edge subset] of solutes with Abraham descriptors was also created.

Results
The first image was created using the full dataset of nodes and edges. Layout is 'Force Atlas,' with attraction strength changed to 1.0. The edges were weighted according to concentration and the nodes were colored and sized according to degree. Node labels were turned on and sized according to degree. The second image was created from the same dataset of nodes but includes edges only to solutes with Abraham descriptors. Only the connected solutes are shown using the degree range filter. In the layout pane, attraction distrib. was checked and attraction strength was set to 3.0. Edges were weighted according to concentration and nodes were sized, coloured and labelled according to degree.

Conclusion
Gephi is a very useful tool for visualizing data and it is our hope, in future work, to use it as an aid to discover new relationships in science by analyzing Open Data from Open Notebook Science projects.
