Overview
Script for generating all gallery thumbnail images used in the Yellowbrick documentation website.
Description
The gallery.py script produces standardized PNG images for Yellowbrick's documentation gallery page. It defines individual functions for each visualizer type (radviz, rank1d, rank2d, pcoords, pca, manifold, scatter, etc.) that create, fit, and save a representative visualization. A helper newfig function standardizes figure dimensions and savefig handles file output.
Usage
Run this script from the docs directory to regenerate gallery images. It is primarily a development tool for documentation maintainers.
