Network Visualization is a technique used to represent complex relationships and interactions within a network. It transforms data into graphical formats, making it easier to understand connections between various elements, such as people, organizations, or systems. By using nodes and edges, it visually depicts how entities are linked, helping to identify patterns and insights. This method is widely applied in fields like social network analysis, biological research, and computer networks. Tools and software for network visualization allow users to create interactive diagrams, enhancing the ability to analyze and communicate information effectively.
