Portland Data Visualization Group #3 April 29, 2010

It's time for another Portland Data Visualization Meetup. The last one occurred on November 3rd, 2009. A number of things have happened since then, like Marshall Kikpatrick's coverage of #pdxboom, the release of Lee Byron's Stacked Graph Source Code and Nathan Bergey's release of his own stacked graph code, Ben Stabler's development of a Flex/Flash data visualization platform and R visualizations, and Aaron Parecki's continued GPS visualization experiments.

We'll have five main presentations from members of the Portland tech community and a bunch of networking time. Webtrends will again graciously host us on their top floor.

The event is open to everyone interested in or working in the field of data visualization. This means designers, programmers, information architects, data miners, anthropologists, ect. We're expecting a similar amount of people to last time (probably around 20-30 people).

Bring a passion for data visualization, and a mind open to exploring new ideas and concepts.
