Visualization Wall at the University of Calgary (TFDL)

10/2/2015

0 Comments

 
The Visualization Studio at the University of Calgary has a VisWall with 34.5 million pixels for a resolution of 9600x3600.  It is 16 feet by 6 feet. The following are some visualizations we just explored using this technology.

About the Visualization Studio:

Publication Dashboard - The following image shows a Publication dashboard generated from the Synthesis literature review software. The top section displays the publication titles on a timeline.  The bottom section shows a variety of aggregated data such as author associations, journal by country (bar, pie, line, stacked bar, etc), and journal by year frequency (treemap). Two visualizations were displayed - Overview of the Canadian Community Health Survey and Overview of Ebola publications.

Forest Ranger - The following visualization shows an automated analysis of the Canadian Community Health Survey. Since there are hundreds of Forest Plots showing the association between outcome and exposure, the VisWall is a good medium for displaying all this data.  When a association looks interesting it can be expanded on the right side of the VisWall. The software that generated these forest plots is called ForestRanger.  
Picture
Verbal Autopsy - The following visualization is displaying a Decision Tree based upon the WHO Verbal Autopsy (VA) questionnaire. The VA questionnaire is 17 pages in length and the goal of this project is to establish a 20 question system in which the questions are asked. At present there are 4,000 pathways (sequence of questions) in this decision tree.
