plot_shapes: plot all shapes provided by internal dataset
Description
These shapes are mainly collected from the package `venn`, and `VennDiagram`.
For Venn plot with more than 4 sets, it is usually impossible to plot with
simple circle or ellipse. So we need to use a predefined coordinates in plot.
Usage
plot_shapes()
