  The process of visually presenting networks is an effective way to understand
entity relationships within the networks since it reveals the overall structure
and topology of the network. Real networks are extremely difficult to visualize
due to their immense complexity, which includes vast amounts of data, several
types of interactions, various subsystems and several levels of connectivity as
well as changes over time. This paper introduces the "MultiViz Plugin," a
plugin for gephi, an open-source software tool for graph visualization and
modification, in order to to visualize complex networks in a multi-layer
manner. A collection of settings are availabe through the plugin to transform
an existing network into a multi-layered network. The plugin supports several
layout algorithms and lets user to choose which property of the network to be
used as the layer. The goal of the study is to give the user complete control
over how the network is visualized in a multi-layer fashion. We demonstrate the
ability of the plugin to visualize multi-layer data using a real-life complex
multi-layer datasets.
