How to visualize your connected big data with graph visualization technology, KeyLines.

1. KeyLines: Interact with your graph
Marco Liberati

2. Why data visualization?
• The user is sitting on the data
• Wants to make meaningful decisions
• A single number is not enough for that

3. Data is invisible
To be seen, data must be
VISUALLY ENCODED
Can I just look at the data?

4. Quantitative Ordinal Nominal

Visual encoding by data type

5. 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?
•What’s the impact of this?

6. There are several design
options for graph visualisation

7. Use a matrix

8. Edge bundling

9. Hive plots

10. Classic node-link

11. I want to visualize a larger
network

12. Deal with big networks is not easy.

13. Here some tips to improve the experience:
•Use colors
•Use filters
•Aggregate nodes and links
•Info on demand
•Expand on demand
