Display system and display method

A display system that displays transitions of users between services accessible using shared user identification information, the display system comprising:

• one or more processors;
• and
• one or more memories storing computer program code and display data, wherein
• the display data is used to display a path diagram in a display area,
• the path diagram includes:
• nodes respectively corresponding to the services;
• and
• links representing the transitions of the users between the services, the links each connecting the nodes to each other,
• the nodes include:
• a first node representing a first service that serves as a reference among the services;
• and
• second nodes respectively representing second services, other than the first service, among the services, and
• the one or more processors are configured to read the program code and operate as instructed by the program code, the program code comprising:
• path diagram display code configured to cause at least one of the one or more processors to display the path diagram in the display area based on the display data;
• and
• node display code configured to cause at least one of the one or more processors to display the nodes in the display area depending on the first service selected from the services.

A display method for displaying transitions of users between services accessible using shared user identification information, the display method comprising causing a computer to display a path diagram in a display area, wherein

• the path diagram includes:
• nodes respectively corresponding to the services;
• and
• links representing the transitions of the users between the services, the links each connecting the nodes to each other,
• the nodes include:
• a first node representing a first service that serves as a reference among the services;
• and
• second nodes respectively representing second services, other than the first service, among the services,
• an overlap ratio is a ratio of the number of users of one of two of the second services to the number of users who use both of the two second services, and
• the display method comprises causing the computer to change a display mode of the second nodes in proportion to the overlap ratio.
