Recovery.gov Visualization

- Geographical map and table are most common

- Browsing is the main activity being supported

- Comparison is often considered but not fully supported

- Not Suitable for Analytic Task

1. Agency Tree 2. Spatial Tree

How to support EXPLORATION within/across both hierarchies is the key point

* Associated with Census Data

CENSUS data

Capability of Visualizing Dual Hierarchy- Two Treemaps with different hierarchies

-Filtered on the same data- Exploration generated Insights

Spotfire : Initial Analysis

But –- Brushing highlights the entire node- Zooming is not synchronized

TreeCovery:Synchronized Dual Treemap Visualization For Exploring the Recovery Act Report

Contribution to Recovery Act Accountability and Transparency.- Providing Analytic Tool for Investigative Journalists - Identifying Invalid Data

Contribution to Treemap Visualization and Spotfire.- Improving Brushing with Proportional Highlight- Synchronizing Zooming/Filtering- Enhancing Treemap Comparison Feature

Data Preprocessing

• Invalid zip code – 253

• Invalid congressional district – 38

• No prime recipient reported -

Video Demo1. Features2. Sample Discovery

Synchronized Dual Treemaps are a new visualization

Great potential for insight generation

Future work:

Add non-linear color gradient

Add more analysis features like on-the-fly columns

Improve shoebox with more analytic features

CONCLUSION

“TreeCovery is the best analytic tool we’ve seen for the data!” Recovery.gov team @ Synteractive
