1. Real-time interaction and dynamic probing are powerful, helpful tools for analysts. Lead Investigatior: Tobias Höllerer Our approach: Make interaction feasible for large-scale data. Use interaction to predictably explore the data Make these technologies available to every web user WiGis: Web-Based Interactive Graph Interfaces Brynjar Gretarsson, John ODonovan, Svetlin Bostandjiev, Tobias Höllerer www.wigis.net

2. WiGis: Web-Based Interactive Graph Interfaces Brynjar Gretarsson, John ODonovan, Svetlin Bostandjiev, Tobias Höllerer Key Ideas Manage computationally expensive interactive Visualizations. Client-side web browsers have varying computational resources. Heavy processing can be performed remotely. Ajax Techniques used to provide a seamless transition between client and server side processing. Large scale interactive graph visualizations can be provided NATIVELY in a web browser

3. WiGis: Web-Based Interactive Graph Interfaces Brynjar Gretarsson, John ODonovan, Svetlin Bostandjiev, Tobias Höllerer www.wigis.net Collaborations Sought: Researchers / Analysts who have large-scale network data and desire a visual / interactive analysis component.

4. Interactive visualization of 1M+ nodes. Scalable by an order of magnitude more than standard web-based graph visualization tools. Fully Integrated with KDD- Blackbook 2.8.1 WiGis: Web-Based Interactive Graph Interfaces Brynjar Gretarsson, John ODonovan, Svetlin Bostandjiev, Tobias Höllerer www.wigis.net
