Say what you will about circular visualization, but the spiral plays. This one from NASA shows global temperature change over time:

The visualization presents monthly global temperature anomalies between the years 1880-2021. These temperatures are based on the GISS Surface Temperature Analysis (GISTEMP v4), an estimate of global surface temperature change. Anomalies are defined relative to a base period of 1951-1980. The data file used to create this visualization can be accessed here.

This is based on Ed Hawkins’ chart originally from 2016, but watch to the end for some extra sauce.
