Today is a milestone for the NodeXL project: we have had our 200,000th download:

2013-NodeXL-Download Count 200K+

Thanks to the many contributors and users of NodeXL! We plan to continue to develop and freely release the easiest tool for getting insights from networks.

Recent features include a Graph Database server that can store larger networks, content analysis of the text associated with networks, and automated production of network reports.

NodeXL Graph Gallery on the web: Collectively Authored Archives of Networks

07SepMay 7, 2015 By Marc Smith

The NodeXL team from the Social Media Research Foundation has released a web application that allows users to upload network files and download files other users have uploaded.

The Social Media Research Foundation is dedicated to Open Tools, Open Data, and Open Scholarship.

The NodeXL Graph Gallery on the Web enables the research community to collectively gather and share data sets.

Users of NodeXL will notice a new NodeXL>Data>Export>To Web Gallery menu option which opens this dialog box:

Users will be able to browse the NodeXL Web Gallery for graphs that were recently uploaded:

Users will be able to search for graphs that contain certain keywords:

Users can then get details about the network graph and download those files they would like to investigate.

Node and Venn: NodeXL can create Venn Diagrams!

27JanMay 7, 2015 By Marc Smith

NodeXL updated starting with version 1.05 with features that make it fairly easy to create basic “Venn Diagrams”.  A Venn diagram is a familiar way to illustrate the overlap (or lack thereof) of two or more “sets” of things.

There are some very amusing Venn diagrams out there!  This one in particular made me laugh but I may be dating myself.

The Venn diagram feature is a special request from the Microsoft Biological Foundation group.

A Venn is related to but different from an Euler diagram.  An “n-Venn” diagram is a collection of closed curves (“circles”) on a plane where all the circles intersect. A “simple” Venn diagram has just two circles but complex diagrams can have more.  A 2 circle Venn diagram has 3 regions (A, B, A+B) and a 3 circle Venn diagram has 7 regions (A, B, C, AB, AC, BC, ABC).

A Survey of Venn Diagrams can be found at http://www.combinatorics.org/Surveys/ds5/VennEJC.html.

Our implementation is a bit of a hack, we basically let you define the X/Y location of 3 circles.  A richer Venn tool would make it easy to take set data and define these circles.  We may get that implemented in the coming months.

Component Binning: a network layout improvement in NodeXL v.108

14JanMay 7, 2015 By Marc Smith

Network visualizations can be very compelling but they are often a smear of unintelligible nodes and edges without refinement and filtering.  Creating an automated layout for a complex graph is a challenging area of mathematics and computer science.  Several layouts are available and are widely implemented, including the Fruchterman-Reingold layout, the Harel-Koren fast multilevel layout, and a number of geometric designs like circles, grids and trees that can be useful for some data sets.

Improvements to these layouts have been slow in coming: the math behind these layout algorithms have no simple or even best solutions.

Recently, a simple technique has done a great deal to improve many complex network graph layouts by arranging each component in the graph in a grid.  Components are pieces of a network that are not connected to any other component.  These islands come in various sizes, often there is one large or giant component and many smaller “isolates”.  In many layout algorithms these isolates are a problem and are either pushed to the edges of the graph into a circle or ellipse that resembles an “asteroid belt” (Fruchterman-Reingold) or are overlaid on top of all the other isolates (Haren-Koren).  A solution is to collect all the “isolates” and organize them sensibly and within a grid such that each component is laid out within its own territory or cell.

*BEFORE*

*AFTER*

The result is a step towards what Ben Shneiderman refers to as “NetViz Nirvana” – a state in which network graphs are more visually intelligible.  When isolates are binned in a grid, two graphs can be visually contrasted far more than when they each have a smeared “asteroid belt” of nodes.

We have implemented an initial binning layout method in the latest version of NodeXL that simply breaks out each component and places it within a grid based on the number of nodes and edges in that sub-graph.  I can imagine more sophisticated approaches would locate each sub-graph based on a range of attributes.

I think the improvement in network visualization is significant.  Isolates no longer impose a big effect on the giant component which often was compacted and compressed as a result of even a single isolate.
