1. A computer system comprising: at least one processor; and a memory storing: a data graph including a plurality of first entities of a first entity type, wherein the first entity type has a first property of an alpha-numeric type, wherein at least some of the first entities have respective alpha-numeric values for the first property, and instructions that, when executed by the at least one processor, cause the system to: generate data used to display the data graph in a tabular format, where entities of the first entity type are displayed in a first column and the first property is displayed in a second column, receive a selection of the second column, receive, responsive to the selection of the second column, a new entity type for the first property from a user, generate second entities having the new entity type, each second entity representing a unique alpha-numeric value for the first property from the respective alpha-numeric values, and for a particular first entity of the plurality of first entities: generate a labeled relationship in the data graph between the particular first entity and one of the second entities based on the alpha-numeric value of the first property for the particular first entity, the label being based on a heading of the second column, and upon generating the relationship, remove the first property from the particular first entity.

The system of claim 1 , wherein the memory further stores instructions that, when executed by the at least one processor, cause the system to: receive an existing entity type as the type for a second property; determine that a certain first entity has an alpha-numeric value for the second property that corresponds to an entity of the existing entity type; generate a relationship in the data graph between the certain first entity and the entity of the existing entity type, the relationship representing the second property; and remove the second property from the certain first entity.
