A system and method for modeling code segments that do not have a location is disclosed. Source code may be indexed and modeled in a data graph with nodes representing code elements and edges representing relationships between nodes. However, some code elements may be hidden or implicit and therefore may lack location information. In these cases, code figments are created and represented as nodes in the graph. Figment nodes may be specially designated so that the figment nodes may be easily distinguished from real source code nodes. The graph is then updated to include location information for the code figments in the nodes that interact with the hidden or implicit code. The data graph may then be provided to a user or as a service to be used by coding tools.
