75    Focus+Context (fisheye) views\cite{fc-fisheye} are one paradigm for viewing large,
76    structured information sets
77    which has gained popularity in the research community\cite{XXX}
78    but less so in production systems.
79    
80    The basic principle in Focus+Context views is that of showing the current area of
81    interest (focus) magnified, and the structurally connected elements with less magnification.
