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 means 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 .
