“…Nodes and edges in the network usually represent individuals (components) and connections between them in the system [ 23 , 24 ], respectively. Complex networks have been widely applied, for instance, identifying influential individuals in the spread [ 25 , 26 ], analyzing the dynamics of the ecosystem [ 27 – 30 ], studying synchronization control [ 31 , 32 ], and discovering properties of complex systems [ 33 , 34 ]. Interdisciplinary research has also been carried out to strengthen the ability of complex networks to solve problems in combination with other disciplines, including entropy [ 35 , 36 ], fuzzy theory [ 37 , 38 ], game theory [ 39 , 40 ], machine learning [ 41 ], evidence theory [ 42 – 44 ], and information fusion [ 45 – 47 ].…”

The analysis of time series and images is significant across different fields due to their widespread applications. In the past few decades, many approaches have been developed, including data-driven artificial intelligence methods, mechanism-driven physical methods, and hybrid mechanism and data-driven models. Complex networks have been used to model numerous complex systems due to its characteristics, including time series prediction and image classification. In order to map time series and images into complex networks, many visibility graph algorithms have been developed, such as horizontal visibility graph, limited penetrable visibility graph, multiplex visibility graph, and image visibility graph. The family of visibility graph algorithms will construct different types of complex networks, including (un-) weighted, (un-) directed, and (single-) multi-layered networks, thereby focusing on different kinds of properties. Different types of visibility graph algorithms will be reviewed in this paper. Through exploring the topological structure and information in the network based on statistical physics, the property of time series and images can be discovered. In order to forecast (multivariate) time series, several variations of local random walk algorithms and different information fusion approaches are applied to measure the similarity between nodes in the network. Different forecasting frameworks are also proposed to consider the information in the time series based on the similarity. In order to classify the image, several machine learning models (such as support vector machine and linear discriminant) are used to classify images based on global features, local features, and multiplex features. Through various simulations on a variety of datasets, researchers have found that the visibility graph algorithm outperformed existing algorithms, both in time series prediction and image classification. Clearly, complex networks are closely connected with time series and images by visibility graph algorithms, rendering complex networks to be an important tool for understanding the characteristics of time series and images. Finally, we conclude in the last section with future outlooks for the visibility graph.
