The dataset for this sample is extracted from the [National Center for Biotechnology Information](https://www.ncbi.nlm.nih.gov/) ([FTP source](ftp://ftp.ncbi.nlm.nih.gov/pubchem/Compound_3D/01_conf_per_cmpd/SDF)). The file format is [`SDF`](https://en.wikipedia.org/wiki/Chemical_table_file#SDF). Here's a more detailed description of the [MDL/SDF file format](http://c4.cabrillo.edu/404/ctfile.pdf).
