Fig 4 — The factor-graph for a library of 15 compounds is shown immediately below an associated NMR spectrum. Each factor is represented by a square and each variable using a circle. Concentration (larger circles) and shift variables (smaller circles, beside the associated concentration) corresponding to each compound appear together. The position of each factor $f_{I}$ position in the plot corresponds to the center of the corresponding block .
