One way to visualize the association of semi-structured data is to show the structure of its schemas. We developed an interactive service system using of a method for self-organizing schema structure, an application of self-organizing mapping. A graph structure is generated by estimating data association as a link between field names in relational tables. This facilitates exploratory visualization in data lakes. Experiment results obtained with a prototype system demonstrated the method's practicability.
