In state-of-the-art libraries (for example, Standard Template Library), they support a number of data models, such as set, map, sequence, etc. Since graph data processing is widely used in combinatorial processing and optimization programs, in this research, we implemented software design of a graph model with extended views. In the design, we developed various graph data models with associated graph operations and graph algorithms. With this library, we can support program designs utilizing graph data and processing.
