# Atlas files

    Atlas files contain a collection of map assignments. 

## The files contained here are : 

    * Atlas.py

        This is the main Allas reader Library 

    * test.jsonl.gz

        This is a small hand made collection of map assignments for testing.

        Notice that it is compressed. The library can read compressed or uncompressed files.

    * truncated_nc_multiscale.jsonl

        This is part of a real Atlas file for testing. It is uncompressed. This file is stored in a multi-scale format which keeps counties whole if they are all assigned to the same district. 

    * pct21_20cen_wMCD.json, pct21_20cen_wMCD_updated.json

        This contains some election data and the adjacency data. The second files as some more recent election data

        Some helper functions that are useful.
