A mechanism for interacting with code such as software code is provided, whereby the code is represented as a graph such as a finite state machine corresponding to the code, such that a user may define a path through the code for example by way of a gesture or cursor movement, and the representation of the graph being restructured to give prominence to the nodes belonging to the defined path, and their sequence as defined in the path. The underlying code associated with each node may be presented with each corresponding node, so that the code of the nodes in the path is aligned, and can be read through as a continuous text. Amendments made to the code as presented can be reintegrated, and the representation adjusted as necessary.
