| Short | Email network from a EU research institution |
| Vertex type | User |
| Edge type | |
| Format | Undirected |
| Edge weights | Unweighted |
| Description | The network was generated using email data from a large European research institution. Nodes are users (of a unique email address) and edges are emails between two users. Note edges are undirected and thus indicate that both users have sent/received emails to one another. See email-EU-dir for the directed version. |

Interactive Visualization of Node-level Properties and Statistics
Tools for Interactive Exploration of Node-level Statistics
Visualize and interactively explore ia-email-EU and its important node-level statistics!
- Each point represents a node (vertex) in the graph.
- A subset of interesting nodes may be selected and their properties may be visualized across all node-level statistics. To select a subset of nodes, hold down the left mouse button while dragging the mouse in any direction until the nodes of interest are highlighted.This feature allows users to explore and analyze various subsets of nodes and their important interesting statistics and properties to gain insights into the graph data
- Zoom in/out on the visualization you created at any point by using the buttons below on the left.
- Once a subset of interesting nodes are selected, the user may further analyze by selecting and drilling down on any of the interesting properties using the left menu below.
- We also have tools for interactively visualizing, comparing, and exploring the graph-level properties and statistics.
