  While many visualization researchers have attempted to define data insights,
little is known about how visualization users perceive them. We interviewed 23
professional users of end-user visualization platforms (e.g., Tableau and Power
BI) about their experiences with data insights. We report on seven
characteristics of data insights based on interviewees' descriptions. Grounded
in these characteristics, we propose practical implications for creating tools
that aim to automatically communicate data insights to users.
