Web interface consists of several main elements: Navigation panel, Main toolbar, Main screen and Views panel.
Navigation panel is the tree representation of all objects and links available.
Main screen displays information the user chooses (objects map, information about object and others).
Main toolbar contains controllers for the main operations under the objects such as creation, cloning, deleting and others.
Views panel allows to hide the navigation panel and switch views on the main screen.
The states of objects and the links between them are displayed by colors in the system web interface. You can see the «object color — object state» association in states list.
