Slides of my talk at IBM CAS University days 2011 on Choosel.

1. Choosel – Modular Web-based
Visualizations
Lars Grammel
PhD candidate, CHISEL Group, University of Victoria

2. What is Choosel?
Extensible, modular open source framework
for creating and working with
multiple coordinated view visualizations on
the web
Pre-configured Visual data exploration
visualizations workbenches
http://code.google.com/p/choosel/ 2

3. How can Choosel be used?
Visual Data Exploration Workbench
Choosel workbench tailored towards a specific domain
Fixed Multiple Views Visualization
Custom multiple coordinated views visualization for a
specific scenario
View Embeds on the Web
Single views exported from workbench
Choosel Views in Other Web Applications
GWT applications that use Choosel views to show
information

9. Visual Data Exploration Workbenches
• Multiple windows
• Customizable view
content and visual
mappings
• Persistent and sharable
workspaces
• Selections and filtered
views
• Undo & redo
• Note taking
• View sharing

13. Pre-configured Visualizations
Freedom for designer:
• Screen layout
• Integration of views with
additional content and
widgets
• Color choices and theme
• Visual mappings
• Interaction and
Coordination design
• Details-on-demand

15. Summary
• Choosel is an extensible, modular open source
framework for multiple coordinated view
visualizations on the web
• Choosel can be used for:
– Visual data exploration workbench
– Pre-configured web visualizations
– Embedded visualizations in GWT applications
