REVIGO Summarizes and Visualizes Long Lists of Gene Ontology Terms
Blue and green bubbles are GO terms with more significant p-values than the orange and red bubbles. The bubbles' x and y coordinates were derived by applying multidimensional scaling to a matrix of the GO terms' semantic similarities; consequently, their closeness on the plot should closely reflect their closeness in the GO graph structure i.e. the semantic similarity. The cluster representatives (see legend of Fig. 6) have their description printed on a dark background, while the other cluster members' descriptions have white backgrounds.
