Chord diagram displaying the connections between the eleven descriptors of the database. The thickness of a connection is proportional to the number of molecules belonging to both descriptors. The semi-elliptical area that is only about its starting descriptor is proportional to the total number of molecules smelling like that descriptor. Therefore, comparing the width of this area and the arc allows us to estimate the number of molecules smelling only like that descriptor. Most of the molecules of the upper half have connections to the descriptors ‘fragrant’, ‘aromatic’ and ‘sweet’ that are displayed in the lower half
