The CCA has posted a link to this neat animated GIF showing, state-by-state, the occupant of the White House's approval rating. This wouldn't be hard for a newspaper to do, and it's easily updated.
Following the 2000 and 2004 U. S. presidential elections, the red-blue divide has frequently been talked about and mapped, so much so that the map has become ubiquitous on the Internet (see 1, 2, 3 and so on). Radical Wit has posted an animated gif map of the country showing George Bush’s approval ratings using the same partisan colours as the election results maps. The map begins with the 2004 election and changes every five seconds to the next month. Maps of individual maps are also available as static images.
Martin Dodge, he of “Mapping Cyberspace” realm, sends along this helpful post:
“Hello, I've just been browsing through a fascinating new book on maps and spatialisations, many of networks, info spaces and online conversations.
“It has many interesting essays and a rich array of illustrations.
“Else/Where: Mapping: New Cartographies of Networks and Territories edited by Janet Abrams and Peter Hall see http://design.umn.edu/go/project/elsewheremapping“
And Martin's e-mail took us, eventually, to The Design Institute at the University of Minnesota. Drill down in the DI site a bit: a lot of interesting resources and topics for those of us interested in data, networks, infographics, user interface, IA, etc.
The Design Institute (DI) develops advanced research, educational programs and interdisciplinary partnerships to improve design in the public realm.
Established as one of the University of Minnesota's Strategic Interdisciplinary Initiatives, with recurring funds from the Minnesota Legislature, the DI addresses products, systems and environments, as well as the underlying social processes that bring our everyday material landscape into being.
The DI is particularly interested in the design implications of emerging technologies — in the nexus of communications media and public space.
Looking beyond issues of styling, the Design Institute regards design as a strategic mode of thinking, a form of conflict resolution whose tangible outcomes express successful negotiation of diverse values and interests.
The Design Institute's Fellows program, workshops, publications and events foster new models for collaboration between diverse fields of inquiry.
By supporting the development of new prototypes, and enabling young practitioners to create their next significant work, the DI champions expanded design choices to enhance citizens' lives, in Minnesota and nationwide.

We should have caught this on Friday, but….
Patrick Radden Keefe (The Century Foundation) offers up a good overview of the pros and cons of Social Network Analytis in last Friday's (12 March 2006) edition of The New York Times. In “Can Network Theory Thwart Terrorists?” he says that “the N.S.A. intercepts some 650 million communications worldwide every day.” Well, that's a nice round number, but one so large that we wonder how, for example, to account for basic variables such as the length of call? (You don't suppose the good folks at the N.S.A. have to wait while the “Please wait. A service technician will be with you shortly” messages are being replayed for 18 minutes, do we?)
We think Social Network Analysis is another of those tools in its infancy, but one with (a) great potential and (b) an equally great development curve.
Just received a reference to this gallery of network visualizations. The site is new to me, but perhaps not to all of you. http://www.visualcomplexity.com/vc/index.cfm
Be sure to drill down in the “About” link for additional riches. There are hints of potential here but for the fact that much of the design is in the ever-so-cool black and gray, which means it's a chore to extract any meaning. ___________________________________________________
Goal VisualComplexity.com intends to be a unified resource space for anyone interested in the visualization of complex networks. The project's main goal is to leverage a critical understanding of different visualization methods, across a series of disciplines, as diverse as Biology, Social Networks or the World Wide Web. I truly hope this space can inspire, motivate and enlighten any person doing research on this field.
Not all projects shown here are genuine complex networks, in the sense that they aren’t necessarily at the edge of chaos, or show an irregular and systematic degree of connectivity. However, the projects that apparently skip this class were chosen for two important reasons. They either provide advancement in terms of visual depiction techniques/methods or show conceptual uniqueness and originality in the choice of a subject. Nevertheless, all projects have one trait in common: the whole is always more than the sum of its parts.
How it started
The idea for this endeavor started on my second year MFA program at Parsons School of Design. During this period I conducted extensive research on the visualization of complex networks, which culminated with my thesis project Blogviz: Mapping the dynamics of information diffusion in Blogspace. One thing I found while exploring this area was the lack of an integrated and extensive resource on this subject. This is the main reason why this project came to life.
Later on, as a teaching assistant of Information Architecture at Parsons Design+Technology program, together with Christopher Kirwan, I was able to consolidate most of this research as part of an independent study. The key chunk of projects shown here was gathered during this phase. My ultimate goal is to keep adding new projects to a still undetermined limit.
Introduction to social network methods
Table of contents
This on-line textbook introduces many of the basics of formal approaches to the analysis of social networks. The text relies heavily on the work of Freeman, Borgatti, and Everett (the authors of the UCINET software package). The materials here, and their organization, were also very strongly influenced by the text of Wasserman and Faust, and by a graduate seminar conducted by Professor Phillip Bonacich at UCLA. Many other users have also made very helpful comments and suggestions based on the first version. Errors and omissions, of course, are the responsibility of the authors.

Paul Walmsley, a programming wiz at IRE, has developed a neat PERL script for doing a bit of Social Network Analysis online at the IRE site.
“JustLooking” is a members-only tool that has been up for a year, Walmsley said, but lacking publicity, it’s been pretty much backstage. The app is a relatively basic, yet impressive tool whose results are designed to be integrated/imported into UCInet, an early SNA tool.
“JustLooking” comes, so far, with two network templates to save time in common situations. * Campaign Finance: for tracking campaign dollars * Rolodex: for entering basic networks of people and organizations

Abstract: There are networks in almost every part of our lives. Some of them are familiar and obvious: the Internet, the power grid, the road network. Others are less obvious but just as important. The patterns of friendships or acquaintances between people form a social network. Boards of Directors join together in networks of corporations. The workings of the body's cells are dictated by a metabolic network of chemical reactions. In recent years, sociologists, physicists, biologists, and others have learned how to probe these networks and uncover their structures, shedding light on the inner workings of systems ranging from bacteria to the whole of human society. This lecture looks at some new discoveries regarding networks, how these discoveries were made, and what they tell us about the way the world works. http://www.santafe.edu/events/abstract/276
Reviewer's View: anacubis Desktop is a novel and sophisticated tool for analyzing data—and connections between data and data sources—imported from a wide range of sources and file types, both textual and quantitative. The price is not trivial, and developing anacubis expertise will require climbing a substantial learning curve. But the potential rewards are great for analysts and companies willing to take the long view. http://www.econtentmag.com/?ArticleID=7126
JUNG — the Java Universal Network/Graph Framework–is a software library that provides a common and extendible language for the modeling, analysis, and visualization of data that can be represented as a graph or network. It is written in Java, which allows JUNG-based applications to make use of the extensive built-in capabilities of the Java API, as well as those of other existing third-party Java libraries.
The JUNG architecture is designed to support a variety of representations of entities and their relations, such as directed and undirected graphs, multi-modal graphs, graphs with parallel edges, and hypergraphs. It provides a mechanism for annotating graphs, entities, and relations with metadata. This facilitates the creation of analytic tools for complex data sets that can examine the relations between entities as well as the metadata attached to each entity and relation. http://jung.sourceforge.net/index.html
