This algorithm accepts tabular data and constructs a directed network from entities in a given source column to entities in a given target column.
One node is created for each entity in either column. If the same entity occurs in different places (say "Alice" occurs twice), duplicate nodes are not created – there will be only one "Alice" node. If your cells are multi-valued (as in "Alice,Bob,Charles") you can define a separator (in this example ",") to create three nodes ("Alice", "Bob", and "Charles") rather than one node "Alice,Bob,Charles". This applies to both the source and target columns.
For each row in the table, an edge is formed from each entity in the source column to each entity in the target column.
The properties files for this algorithm are very similar to, but not identical to, the properties files used in Update Network by Merging Nodes. For many pipelines you will need to create similar .properties files for both. Try creating one and adapting it for use in the other.
