Visualizing the US congress – updated April 2018

Vicky Chuqiao Yang, Northwestern University: “This is a interactive visualization I made of the congress members’ ideology positions, reduced to 2 dimensions, using the DW-NOMINATE method. This visualiztaion is developed as part of the IDEAS Focus Summer School on Data Visualization at Northwestern University. How to use this visulaization:

  • Each circle represents a congress member
  • The colors represent party membership
  • Hover mouse over a circle to see name and state of the congress member.
  • Use the slider bar to scroll over years…” [h/t Anne Zald]
