Here at Quartz, we love data and we appreciate the power of a good graph. In fact, we like them so much that our newsroom produced 1,271 of our own as of Dec. 22, 2021!

A few weeks ago, we asked our readers about the charts that best helped them understand the world this past year. We gathered the best ones, along with a few of our own favorites, and compiled them here for you to enjoy.
