Figure 2: Network of predicted anti-cancer plants and anti-cancer drugs

. The network connects plant and drug if the compounds in this plant show similarity with this drug (Tc 0.70, MACCS fingerprint). Two isolated sub-networks were shown in the figure. The red rectangle, green circle, light blue circle and gray circle represent predicted anti-cancer plant, approved drug, clinical drug and preclinical drug, respectively. The lines link the approved drug, clinical drug and preclinical drug are color as green, light blue and gray, respectively. The node size is proportional to the number of connections.
