Visualization of the clustering of compounds in the NCI-60 data. The first two principal components of each of the 244 compounds are used as x and y coordinates to visualize the clustering of the compounds. Compounds closer to each other in the plot represent structurally similar compounds. Amino acid derivatives are highlighted in red, while derivatives of camptothecin are highlighted in blue, while all other compounds are shown in green.
