Easy pie charts and donut charts with ggforce

I make pie charts and donut charts in ggplot2 using a combination of a bar plot and polar coordinates. This works fine but polar coordinates prevent using any other geoms or annotations that need Cartesian coordinates. For example, annoatation_raster doesn't work with polar coordinates. ggforce solves this issue.

Persistence in Mutual Fund Performance

In this article, I reproduce Figure 1 from Mark Carhart's classic 1997 Journal of Finance article titled "On Persistence in Mutual Fund Performance". The visualizations are created using highcharter and echarts4r packages. It is an interactive bar plot that shows that there is a very low persistence in the mutual fund performance.
