Heart-shaped wordcloud, celebrating Colombia peace treaty

This is a lightening quick post just providing the script to draw a heart-shaped wordcloud, using the awesome wordcloud2 package.

The Sankey plots allow for an ‘automatic sorting’ of countries based on who is the water tower and who is the water source. This visualization is useful to demonstrate where a country falls on this continuum. The network plot shows the automatic arrangement of countries with their ‘water-neighbours’ without being… Read more →
