The paper proposes a method for creating a knowledge graph focused on visualization, usage of spreadsheets and group work. A knowledge graph is a set of typed entities (with attributes) related to each other by relationships. Entity, attribute and relationship types are determined by a scheme called ontology. The proposed method was created within the project with an automotive company, which needed systematization, integration and re-use of knowledge about the assembly units of various cars within the company. The created knowledge graph has a complex structure of properties associated with one class and its subclasses, while there is a little number of ontology classes. The need for active involvement of experts in the creation of the knowledge graph determines the scope of the method, since they and their colleagues will use the system in the future (internal customers). The proposed method helped to create a pilot knowledge graph, which includes more than 50 assembly units and about 400 properties.
