Module guide

GerryTools is organized into public modules that can be used independently or together.

Guide	What it provides
Data	Census tables, CVAP estimates, and processed geographic products
Plan comparison	Plan overlap, relabeling, and population dispersion
Plotting	Statistical plots, geographic plots, and Matplotlib composition
Colors	Named colors, district palettes, colormaps, and palette previews
Ensemble runners (MGRP)	Docker-backed Rust ReCom, Forest, and SMC runners
Recording chains (BEN)	Recording and replaying ReCom ensembles with GerryChain
Scoring	In-memory GerryChain scoring and streamed BENDL evaluation
LaTeX output	TeX tables and TikZ-native figures

The modules do not prescribe one end-to-end workflow. A typical analysis might retrieve Census tables with Data, then prepare geometry and a dual graph with Plan comparison. It could generate an ensemble with an MGRP runner or a recorded GerryChain, score the resulting plans, and pass those results to Plotting or LaTeX output. Each guide documents the objects it accepts and the form of its output, so projects can enter that sequence at the stage their existing data supports.
