Let's begin.
The role of data
Data should be seen as a force multiplier in the newsroom (cit. Aron Pilhofer, TheGuardian)
Data empowers existing storytelling processes.
It can help to engage with readers.
It's about questions:
Keep questions brief
Include data in your story if questions are clear in your mind
Break questions down
Bear in mind that all questions will need (at least) a data source
e.g. How many students abandon high schools in Italy?
In Italian provinces?
In professional schools?
Before the 5° year?

Data can be zoomed in/out:
Big picture vs. Local detail
Localize discussions
Let people have insights
Foster comparisons
Engage users
Trigger debates

(and a table is actually «data»)
In order to be transformed into a map, a table needs...
Location column(s)
Location column(s)
