Depicted above are five frames to help you explore information visually.
The five frames are: Node/system, components, comparison, function, change
Why are node and system considered together? Everything that can be considered as a node can also be considered as a system.
A human being, for example, can be thought of as a system, made up of subsystems like the nervous system, circulatory system, etc. A human can also be thought of as a node in a larger system, such as a family, tribe, or society.
See here for a visual that shows how these frames relate to each other.
