Choosel at VisWeek 2010 and at CASCON 2010

Interested in data visualization on the web? There are several Choosel-related events at VisWeek 2010, CSER and CASCON 2010. Choosel is an open-source framework for browser-based data visualization.

Oct 24-28, I will present the InfoVis poster "Choosel – Web-based Visualization Construction and Coordination for Information Visualization Novices" at VisWeek 2010. Here is a preview:

Oct 31st, there will be a presentation on Choosel and the Work Item Explorer at CSER. The Work Item Explorer (developed by Patrick Gorman, Del Myers and Christoph Treude) is a research prototype built on Choosel that facilitates the flexible, iterative exploration of Jazz data, focusing primarily on work items.

Nov 1-4, there will be CASCON exhibits on Choosel and the Work Item Explorer. The Choosel exhibit (Bradley Blashko, Lars Grammel) will be at booth X2 near the Central Tower, and the Work Item Explorer exhibit (Patrick Gorman, Christoph Treude) will be at booth U5. The exhibits are open 5pm to 7pm on Monday (Nov 1), from 8.30am to 7pm on Tuesday and Wednesday (Nov 2 and 3), and from 8.30am to 1pm on Thursday (Nov 4).

Choosel Poster at InfoVis 2010

I will present a poster on the Choosel Framework at IEEE InfoVis 2010. The main goal of the Choosel project is to enable software developers and researchers to easily create web-based visual data exploration environments for novices. The poster paper briefly summarizes some of the related work, the features of Choosel, and the results of a prelimary usability evaluation:

Since information visualization has become increasingly vital to experts, it is now important to enable information visualization novices to consume, construct, and coordinate visualizations as well. Choosel is a web-based environment that aims at facilitating flexible visual data exploration for information visualization novices. It supports the iterative construction of multiple coordinated views during the visual data analysis process. A preliminary user study with 8 participants indicated that multiple windows, enhanced drag and drop interaction, and highlighting of items and sets, in particular, support novices in the visual data exploration process in a useful and intuitive way.

Supporting End Users in Coordinating Multiple Visualizations

As part of my PhD research, I am looking at ways to make visual data analysis more accessible to end users without data analysis expertise. Specifically, I am researching how they can easily coordinate multiple visualizations. This has led to the development of web-based visual analytics research prototype, which I evaluated in a user study. The results indicate that novel concepts such as drop target highlighting, drop previews and using multiple user defined sets are useful and easily usable for end users.

I presented the tool and the results (see poster and presentation below) at the IBM University Days 2010. A version of the visual analytics environment that is tailored to exploring biomedical ontologies is available at: bio-mixer.appspot.com
