Data:
• Focus: 45 fishes– The diet matrix (45 by 45 mat)– Their population at 648 discrete time points before and after fishing strategy applied (two 45 by 648 mat)
Task and Infovis Solution 1:• Task: Find the related fishes of a specific fish
• Solution: Brushing and highlighting
Task and Infovis Solution 2:• Task: Evaluate the effect of human’s fishing
• Solution: Difference graph
High Level Implementation:
• Programming Platform: Visual Studio.Net
• Graphics Package: Zedgraph
• Clustering Algorithm– Distance Measure:
(Root Mean Square)
2 /rms i iD Y X M
Unfinished/Future Work:
• Repeated Colors
• Overlapping reduced but still not eliminated
• Code Optimization
• More user interaction
Lessons learned:
• Understanding users’ preferences
• Developing based on an existing framework or using a visualization package
