Synergy Maps \cite{Lewis_2015} visualizes synergistic activity extracted from screens of drug combinations.   VIDEAN (visual and interactive descriptor analysis) \cite{Mart_nez_2015} is a visual tool for choosing a subset of descriptors appropriate for predicting a target property with aid of statistical methods. Descriptor selection and model building are performed iteratively at the direction of the user.  WCSE (Wikipedia chemical structure explorer) \cite{Ertl_2015} runs as a web application and provides a 2D interface for visualizing and searching for 2D molecules.
