“…A horizontal visibility graph (HVG) [17] constitutes a paradigmatic complex network representation of sequential data, typically used to reveal order structures within the data set [8,35]. HVG-based algorithms have been employed to characterize fractal behavior of dynamical systems [21,31], study canonical routes to chaos (see [24] and references therein), discriminate between chaotic and stochastic time series [26], and test time series irreversibility [33]. There is a growing body of literature using these combinatorial data analysis techniques in applied fields such as optics [1], fluid dynamics [22], geophysics [30], physiology and neuroscience [18,27], finance [25], image processing [13], and more [8,35].…”
