Finds: the Sunlight Foundation and government data

The Sunlight Foundation is dedicated to making political and government information visible. It has a number of links to these types of data sets as well as its own API. Their LOUIS data set is particularly interesting, including the Congressional Record, Reports and Hearings, as well as bills and resolutions, GAO Reports, the Federal Register and executive orders and proclamations. Best of all, LOUIS has an API.

They've produced an interesting series of visualizations of earmarks using IBM and Martin Wattenberg's ManyEyes, and have other visualizations in development. An interesting widget shows words from a recent day in congress. A related site is MapLight, which focuses on bills, laws, and their relationship to money.



Meets: on FeedViz

Hi folks,

We met today and dissected our FeedViz project. You can find some fairly old imagery of it here. The current goal is to send off a poster abstract to IEEE InfoVis by Tuesday.

We recorded a number of thoughts, especially about the coming abstract, in the lab wiki. Among other things, we learned about the difference between Venn and Euler diagrams (FeedViz is closer to Euler).

Meets: ACM CHI -- zooming in

Hi folks,

Let's close out our consideration of CHI by zooming in on two topics: visual information design and awareness/interruptibility.

We probably won't get to all of these, but it's good to have this list regardless. (Note there are a few related to these that we've already skimmed).




Visual information design:

Supporting the analytical reasoning process in information visualization
Yedendra Babu Shrinivasan, Jarke J. van Wijk

Metrics for measuring human interaction with interactive visualizations for information analysis
Theresa A. O'Connell, Yee-Yin Choong

An exploratory study of visual information analysis
Petra Isenberg, Anthony Tang, Sheelagh Carpendale

AutoCardSorter: designing the information architecture of a web site using latent semantic analysis
Christos Katsanos, Nikolaos Tselios, Nikolaos Avouris


The buzz: supporting user tailorability in awareness applications
James R. Eagan, John T. Stasko

Emotion rating from short blog texts
