Introduction• Sometimes imaging software by default enables us to create

beautiful visualizations. • However, designing visualizations that are readable and

provide key insights is much more difficult. • As visualization designers, we are “melding the skills of

computer science, statistics, artistic design, and storytelling” (Cukier, 2010, para 3). – See http://www.economist.com/node/15557455

Tip 2• Provide a context for your findings.• Without context, data is meaningless. • In the example on the next slide, an insight

is communicated that puts the # position (Shanghai) in context and provides an explanation for the rise to the top.

Since 2004 the capacity at the Port of Shanghai has grown from 14 million TEUs to more than 32 million in 2013, giving rise to its # 1 position in terms of TEU volume.

Tip 3• Present the key numbers.• It is important to summarize the key findings and present the

numbers in a meaningful context that is comprehensible to the audience.

• For example, it may be more helpful to show a percentage change from year to year when presenting an increase over time, rather than with absolute numbers.

• Specifically, if the core point is to compare the change from year to year, percentage change is an effective metric as illustrated in the next slide.
