  Recently, a complex network based method of Visibility Graph has been applied
to confirm the scale-freeness and presence of fractal properties in the process
of multiplicity fluctuation. Analysis of data obtained from experiments on
hadron-nucleus and nucleus-nucleus interactions results in values of
Power-of-Scale-freeness-of-Visibility-Graph-(PSVG) parameter extracted from the
visibility graphs. Here, the relativistic nucleus-nucleus interaction data have
been analysed to detect azimuthal-anisotropy by extending the Visibility Graph
method and extracting the average clustering coefficient, one of the important
topological parameters, from the graph. Azimuthal-distributions corresponding
to different pseudorapidity-regions around the central-pseudorapidity value are
analysed utilising the parameter. Here we attempt to correlate the conventional
physical significance of this coefficient with respect to complex-network
systems, with some basic notions of particle production phenomenology, like
clustering and correlation. Earlier methods for detecting anisotropy in
azimuthal distribution, were mostly based on the analysis of statistical
fluctuation. In this work, we have attempted to find deterministic information
on the anisotropy in azimuthal distribution by means of precise determination
of topological parameter from a complex network perspective.
