|  | ## Transition Graph

#### Synopsis

Creates a graphical representation of transitions defined by source and target attributes.

#### Description

This operator creates a transition graph from the given example set. The example set must have a specific structure with (at least) two columns where one column specifies the source of the transition and the second column specifies the target of the transition. Optionally, a third column can be specified in order to define the strength of the transition (this column can for example store the number of times this transition occurred after an aggregation).

The parameter "node_description" will be used for displaying information about the nodes if the information is made available via an example visualization operator. The string might contain macros pointing to attribute names.

#### Input

- example set: expects: ExampleSet, expects: ExampleSet, expects: ExampleSet

#### Output

- example set:
- transition graph:

#### Parameters

- source attribute: The name of the attribute defining the sources of the transitions.
- target attribute: The name of the attribute defining the targets of the transitions.
- strength attribute: The name of the attribute defining the strength of the transitions.
- type attribute: The name of the attribute defining the type of the transitions.
- node description: The description of each node where columns from the example data can be used by the macro form %{COLUMN_NAME}.
