A small collection of scripts and visualization used in my Partisanship in Pizzaville blog post. Read more here: http://ryanjsloan.com/2017/partisanship-in-pizzaville/
Very simple python scripts that illustrate Principal Component Analysis on a matrix of legislators and votes. Requires pandas and sklearn.
Contains an interactive widget built with d3.js which allows you to manually update weights on votes and watch how the partisan scores change.
