A graph whose vertices represent atoms and whose edges encode selected bonding or connectivity relations while omitting most metric and electronic detail.

This is an authored directed relation from the source endpoint to the target endpoint.
Constitutional isomers have distinct atom-connectivity graphs despite sharing a molecular formula.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

A molecular graph retains constitution while abstracting away coordinates, vibrations, and most electronic structure.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.

A molecular graph specializes graph structure with chemical vertex and edge labels for selected atoms and bonds; it deliberately omits coordinates and most electronic information.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.
