Use head-to-head duel statistics data to display a rating graph
This script leverages the data collected by the Geoguessr head-to-head duel statistics script to display your rating graph over time on your own profile page and a team rating graph on each of your teammates' profile pages. It adds a "rating graph" button and a means to select a time range to the profile header, and upon click of the button queries the relevant data from your duels database and generates a graph.
You must have Geoguessr head-to-head duel statistics installed and running in version 0.4.2 or higher for this script to work, as it is that script that downloads the necessary data and stores it in your browser. For team duels support, you need to be running at least version 0.4.3. For the refresh button to work, at least version 0.4.8 is required.
