The Data Team Making complicated things understandable and engaging
The Herald was two Wellington based data journalists - Keith Ng and Chris Knox Feel free to ping us via email, slack, twitter or the phone Or use a zoom call to have us walk you through chart creation What is data journalism? Paul Bradshaw from Birmingham City University says:
Data can be the source of data journalism, or it can be the tool with which the story is told — or it can be both.
The Bureau of Investigative Journalism says:
Data journalism is simply journalism.
The former is a new and trendy term but ultimately, it is just a way of describing journalism in the modern world.
Why use data in stories? Data is the story Fact-checking/importance checking Context Trust Clarity and/or conciseness Engagement Data is a source Trust your instincts Don’t use it out of context One number by itself is often misleading Be skeptical What does data give the narrative? Narrative/Cognitive tension?
Not sure exactly what to call it - but I think it is important.

Chart choice Different charts will highlight different aspects of your data more effectively. Choose the chart that shows the aspect of the data that you are interested in Line and Bar charts are often a safe choice Take care with maps and pie charts FT Visual Vocabulary
Bad or deceiving charts Charts and graphs can be used to deceive The best way to get a sense for bad charts is to peruse vis.wtf or /r/dataisugly . There is also a good writeup here
The most common bad things are:
Incorrect, missing, or misleading labels Inconsistenct scales Truncating scales Comparing things that shouldn’t be Too many things A few rules Barcharts always start at 0 Line charts don’t need to start at 0, but always ask yourself if the range you select is going to
make an insignificant change look important Only use pie charts for parts of a whole and only when there are less than 5 categories Avoid maps for showing quantities LABELS titles, captions, and labels are what guide readers into your chart
