Visualizing Sunspot Numbers

For the visualization, I wanted to create a way to  explore the Sun’s activity using sunspot numbers. The more sunspots in a  year, the more solar activity is seen through solar flares and coronal  mass ejections. Year-by-year, this becomes an excellent way to discover  the variability of our closest star.

Radial charts are  ideal vehicles to show data that might be cyclical. More than 26,000  days are a part of the dataset so performance is impacted with a  sluggish load time. Also drawing the labels and ticks seems to take more  time because of the cartesian geometry.
