The compressed graph mapped to an RNA structure. a The main RNA elements are compressed into vertexes where each vertex represents an RNA loop element, or a stem base pair. b The nucleotides belonging to each RNA element are drawn on top of the underlying RNA compressed graph. c The resulting RNA representation contains less vertexes than there are nucleotides (in this case 120 nucleotides versus 34 vertexes), and a more familiar visual layout
