 With atoms being nodes and bonds being edges, molecular graphs are among the core objects for study in drug discovery. 
 As drug discovery is known to be costly and time consuming, deep learning on graphs can be potentially beneficial for

+To make it easy for domain scientists, the DGL team releases a model zoo for Chemistry, focusing on two particular cases 
+-- property prediction and target generation/optimization. 
 
 With pre-trained models and training scripts, we hope this model zoo will be helpful for both
 the chemistry community and the deep learning community to further their research.
