A folding graph is a connected component of a protein graph. Here you can search for all visualizations of the different folding graph types of a protein chain. For each of the folding graph types (e.g., the alpha graph, which only considers alpha helices),
there are four different visualizations available:

- the ADJ notation: all SSEs of the protein graph are shown, order is from N-terminus (left) to C-terminus, and each edge represents a 3D contact between a pair of SSEs.
- the RED notation: only SSEs of the folding graph are shown, order is from N-terminus (left) to C-terminus, and each edge represents a 3D contact between a pair of SSEs.
- the SEQ notation: all SSEs of the protein graph are shown, order is from N-terminus (left) to C-terminus, and each edge represents the sequential order in the folding graph.
- the KEY notation: only SSEs of the folding graph are shown, order is spatial, and edges follow the SSEs in sequence order (N to C terminus). Note that it is not possible to define a spatial ordering for bifurcated graphs, so such graphs do not have a KEY notation.
