Scaffold Visualizer is an interactive tool for scaffold-based hierarchical visualization of chemical space.
A demo instance of Scaffold Visualizer is available at http://scaffvis.projekty.ms.mff.cuni.cz:9000/
The visualization uses a Pubchem based scaffold hierarchy as a background. This background hierarchy can be downloaded independently in CSV format from http://scaffvis.projekty.ms.mff.cuni.cz/hierarchy.7z. Please note that this hierarchy export is supposed to be used for independent research and can not be directly used by Scaffold Visualizer.
