Embodiments of apparatus, systems, and methods are described for creating, arranging, and displaying data mappings between two different data schemas in a graphical user interface (GUI). The GUI allows scaling of a data schema, automatic data sorting and grouping of objects in a schema, dynamic spacing of data mappings in the GUI, and customizable data map transformations to entities of a canonical data model. The GUI can limit the display of objects and fields to those that have been mapped into entity groups. The GUI can display mapped or unmapped fields to facilitate the mapping of additional fields or objects. The GUI displays visual logic connectors between objects and entities to summarize the relationship and number of mappings between the objects and entities. Objects and entities can be expanded and collapsed to show more granular relationship information. Instance-enabled canonical entities can be created to conceptually group fields.
