The empirical distribution of ATC codes at the top level (Pie chart) and at the second level for each of the fourteen anatomical groups in a dataset of 2232 compounds from the ChEMBL used in this study. The pie chart presents the distribution of ATC codes at the anatomical group-level. The bar charts present the distribution of compounds within each of the anatomical groups. It is apparent that each anatomical group has a characteristic distribution, which becomes increasingly specific as one traverses the ATC hierarchy
