A graph is an abstract structure that is used to model information.
Many real-world situations can conveniently be described by means
of graphs. Smaller area of a drawing increases the readability of
the drawing. Compact drawing of a circuit is preferable for VLSI
fabrication since a compact drawing helps us to avoid wasting of
valuable wafer space. This book deals with area efficient
straight-line drawings of planar graphs. We have introduced some
classes of planar graphs that admit straight-line grid drawing with
sub-quadratic area. We introduce doughnut graphs,'' a subclass of
5-connected planar graphs as well as 3-outerplanar graphs, which
admits a straight-line grid drawing on a grid of area O(n). We
introduce a subclass of 4-connected planar graphs that admits
straight-line grid drawing with linear area. We also introduce a
subclass of outerplanar graphs, which we call label-constrained
outerplanar graphs,'' that admits straight-line grid drawings with
O(nlog n) area. We give linear-time algorithms to find such
drawings. We also give linear-time algorithms for recognition of
these classes of graphs.
