Query: What-Why Analysis of Expert Interviews: Analysing
  Geographically-Embedded Flow Data   In this paper, we present our analysis of five expert interviews, each from a
different application domain. Such analysis is crucial to understanding the
real-world scenarios of analysing geographically-embedded flow data. The
results of our analysis show that similar high-level tasks were conducted in
different domains. To better describe the targets of these tasks, we proposed
three flow-targets for analysing geographically-embedded flow data: single
flow, total flow and regional flow.
