How does it help reach our goal?
We visualise to correctly inform people: dissemination We visualise to draw attention: entertainment

The importance of data simplification
– Advantages vs. Disadvantages
+ accessible, media ready, transparant, flexible - Loss of depth, unsound practices, interpretation
– Lying with statistics still applies! However……
– “lying”, highlighting or simplification
– Misunderstanding works both ways

The importance of data simplification
1. Who are your stakeholders
2. Different needs means different solutions
3. Facilitate analysis: simple, transparent & flexible data

Lesser of two evils: practical problems
– Colour usage: associations with colour
– Zooming of graphs: start from 0?
– Cherry picking data: Highlighting or cherry picking?
– Data-oversimplification/complexity: one for all, full
disclosure and…margins?
– Making the news in the way you want
