Using polylabelr to find visual centers of polygons and label Euler diagrams

A better algorithm for finding a subset of points that maximize the minimal distance between them.

This is an introduction to my package, eulerr, an R-package that computes and plots Euler diagrams for set relationships.

Let me introduce qualpalr: an R package that generates qualitative color palettes with distinct colors using color difference …
