• The user is sitting on the data

• Wants to make meaningful decisions

• A single number is not enough for

Why graph visualization then?

Graphs can give better answers to

these kind of question:

•What depends on what?

•What’s the flow?

•Where are bottlenecks/risks?

There are several design options for graph

visualisation

Use a matrix

Edge bundling

Hive plots

Here some tips to improve the experience:

•Use colors

•Use filters

•Aggregate nodes and links
