The process of converting DNA storage codes into graph data, the forward transformation can be used in the training process, and the reverse transformation can obtain the DNA storage codes that satisfy the constraints

Where the black dots (positive samples) represent DNA storage codes that satisfy the constraints, and the white dots (negative samples) represent those that do not. Edges are connected between points that meet the constraints, and some edges that may be crossed are omitted for clarity, and only positive samples are labeled.
