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.

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
