Cumulative Wikipedia Donations
==============================

This chart shows cumulative donations to Wikipedia over the past 10 years. Inspired by this `Reddit post <https://www.reddit.com/r/dataisbeautiful/comments/7guwd0/cumulative_wikimedia_donations_over_the_past_10/>`_ but using lines instead of areas.
