For the project, I examined the charting of sunspot numbers comparing the usual visualizations of line charts which because of the compressed nature of the x-axis don’t clearly show any cyclical activity except for the well-known 11-year solar cycle. Radial charts, conversely, are well suited to expose other cyclical data. By visualizing individual years, using sunspot number data from the National Solar Observatory between 1945-2017 (1), radial visualizations of sunspot numbers appear to show an underlying cycle.
