1 / 19 Perspective on Visualizing Social Sciences Remco Chang Charlotte Visualization Center UNC Charlotte

2 / 19 Financial Visual Analysis UNC Charlotte’s success with Bank of America and financial visual analytics – Fraudulent Wire Transaction Analysis – “Finding a needle in a stack of needles” – Bill Fox Failure of a blackbox approach The Art and Science of analysis

3 / 19 Financial Visual Analysis

4 / 19 What is Information Visualization? A case study of how a visualization application differs from a visual analytical tool…

5 / 19 Geo-Spatial - LIDAR

6 / 19 Geo-Spatial - LIDAR

7 / 19 Geo-Spatial - LIDAR Identify buildings without permits It’s a useful application… but it’s not an analysis tool.

11 / 19 Geo-Spatial – Urban Analysis DIA presentations mentioned Google Earth’s short coming Demo of UrbanVis

12 / 19 Geo-Spatial – Urban Analysis Query-free Exploration – no need to generate n(n-1)/2 plots to find relationships between every two variables – you don’t have to know what you’re looking for… “Here’s what I’m interested in, there’s where it is” – Combination of data analysis and GIS

13 / 19 Agent-Based Modeling DARPA sponsored project Modeling Afghanistan Using off-the-shelf package (NetLogo) (show NetLogo image)

14 / 19 Agent-Based Modeling

15 / 19 Agent-Based Modeling

16 / 19 Agent-Based Modeling

17 / 19 Agent-Based Modeling Details on demand Juxtaposes different variables for comparison in one glance Allows for multiple resolutions A framework for combining different models Would work great in a collaborative environment such as a multi-touch table

18 / 19 Agent-Based Modeling Visualization is not an after thought… Embed analysis and reasoning directly into the visualization

19 / 19 Interactive PCA Principal Component Analysis (PCA) Based on identifying Eigenvectors and Eigen values Most commonly used in finding clusters Often computed using Matlab or statistical packages (demo InteractivePCA)
