Data visualization, particularly with medical informatics. Although doctors have been demonstrated to think more visually than the general population, health IT physician interfaces are almost exclusively text based. Inspired visual data, medical and otherwise, will be showcased here.

LifeLines for Visualizing Patient Records

1998 work from University of Maryland. The link goes to a Java version you can play with. It's primitive, but its astonishing that electronic medical records haven't evolved into timeline based patient charts.

Unfluence - Political Contribution





Unfluence. This project was built to test the idea of visualizing candidates and their contributors as a browseable network. A sort of quick visual data mining tool for transparency that everyday people can use. Putting the data in a network form also makes it possible to compare patterns of giving across various states and interest groups. A query is generated from your search settings and sent to National Institute on Money in State Politics' API which looks in their databases and returns a list of matching candidates as an xml file. For each candidate they get a list of the top contributors, and discard any with contributions below the value threshold you set. This donor-recipient information is formatted into a network and passed to a program called GraphViz that computes positions for the nodes and draws it (with help from ImageMagik). The image is passed back to you. When you click on a node, they send queries to NIMSP and Project VoteSmart to check if there is information available (this requires some hacked scraping and matching code) for that candidate, and include the links in the info bubble. The visual effects are provided by script.aculo.us.

    VIPIS - Visual Patient Information System Center

    Thank God! There is another group "dedicated to the incubation of novel visual patient information display systems for the Electronic Health Record (EHR)". Located at Visual Information Systems Center at the University of Pittsburgh. Here's a clip from their hot presentation:

    Re: from the 1st WorldVistA Education Conference and Seminar at Robert Morris University near Pittsburgh, Pennsylvania. This is a 3 day education event being put on by worldvista.org Highlights so far, Peter Bodke just demonstrated his VistA demonstration appliance version 1.0 that is available on Sourceforge.


    He discusses: 'Iconic timeline based visualization of clinical data' by Dr. David Eibling and Dr. Augie Turano.


    Discussed inspiration from Edward Tufte's work on presenting data and graphics. Why not build a graphic timeline for pathologies with icons and symbols? See IconoChart.com


    Another phenomenal diagram of a patient timeline was demonstrated by Visual Patient Information System: VIPIS. The implementation is currently in proprietary .net using Intersys Cache object wrappers.


    I agree with Dr. Valdes that "This is clearly the future of where EMR's need to go as it focuses not on just verbage and reports but actually gives you information at a glance. Think beyond dashboards."

    ABSTRACT
    Research on information visualization has reached the
    place where a number of successful point designs have
    been proposed and a number of techniques of been
    discovered. It is now appropriate to begin to describe and
    analyze portions of the design space so as to understand
    the differences among designs and to suggest new
    possibilities. This paper proposes an organization of the
    information visualization literature and illustrates it with a
    series of examples. The result is a framework for
    designing
