Outline

•  What are networks? •  Why visualize networks? •  Visualization techniques – Animation – Color

–  Interactivity

•  What about dynamic networks?

What are networks?

•  A network is a model of interconnected data where the connections are just as important as the data elements

•  Networks are typically modeled as nodes, edges, and properties – when done this way, can be called a “graph”

•  Many technologies exist to work with graphs

•  Graph databases are useful for working with networks but not required. Even key-value pairs can be modeled as networks!

Purpose of visualization

•  To better understand the structure of the data that you are collecting

•  To better understand the relationships contained in the data that you are collecting

Why Visualize Networks?

•  Graph data is inherently visual •  Accessible by non-scientists •  Convey a deeper understanding of data

Why uses graph visualization?

•  Finance and Insurance –  Fraud discovery and investigation

–  Regulatory compliance

•  Information Technology –  Network Topology

–  Risk Assessment

•  Government –  Defense and Intelligence –  Law Enforcement

•  Oil and Gas –  Physical Infrastructure

Creating visualizations

•  Convey Information Through Visual Properties – Nodes

•  Images or Icons •  Colors

•  Sizes •  Glyphs

– Edges •  Colors

•  Width

Add interactivity

•  Query •  Animate - Changes to the chart should be animated so

that the user doesn’t lose track of nodes

•  Layout - The user should be provided with multiple layout options to see what best organizes the data

•  Explore - The user needs to be able to inspect non-visual properties of the nodes and edges

•  Expand - The user needs to be able to add additional data to the visualization

•  Combine and Filter - Not every data element needs to be drawn on the chart at once
