screenshot of exercise 5 in our coordinate system lesson in "ggplot2 unchartred" shwoing the solution which is a ciruclar heatmap of (fictious) traffic data per hour and weekday.

Late for #Day8 of the #30DayChartChallenge, but the "Circular" prompt is the perfect excuse to share yet another #ggplot2 trick! 👀

Tried the "new" #coord_radial yet? Compared to coord_polar, it:

🌀 bends grid lines
🌀 places labels naturally
🌀 allows inner radii
🌀 handles partial circles easily
