Piecharts are highly criticized in dataviz. Use it with care, or even better, use alternatives like barcharts, lollipop plots, treemap and others.
What's wrong with it? Barchart Lollipoppie()
function
The pie()
function is natively provided in
R
. It allows to build nice piechart in seconds. Here is
an overview of its functioning:
ggplot2
package
There is no specific geom
to build piechart with
ggplot2. The trick is to build a
barplot and use coord_polar
to make it circular. This is
why the pie()
function described above is probably a
better alternative.
