I've retired the old Shiny-based app for my R package eulerr (https://https://jolars.github.io/eulerr/) that used to live at https://eulerr.co, which now directs to the new site at https://eunoia.bz.

The new app makes use of the new, exciting features of Eunoia, like supporting a complement (universe), as well as squares and rectangles in addition to circles and ellipses.

Please check it out!

Area-Proportional Euler and Venn Diagrams with Ellipses

Generate area-proportional Euler diagrams using numerical optimization. An Euler diagram is a generalization of a Venn diagram, relaxing the criterion that all interactions need to be represented. Diagrams may be fit with ellipses and circles via a wide range of inputs and can be visualized in numerous ways.

Trying to explain to a non-European colleague about the difference between #GreatBritain and the #UnitedKingdom is such a mess.

Luckily, #Wikipedia has a nice #EulerDiagram for anyone who is interested.

@Zamfr @TestUser42 @errantscience Euler is likely to remain eternally frustrated on this point.

Helps in naming of certain groupings of islands, although it might be seen as a controversial groupings for some…

“An Euler diagram is a diagrammatic means of representing sets and their relationships. They are particularly useful for explaining complex hierarchies and overlapping definitions. They are similar to another set diagramming technique, Venn diagrams. Unlike Venn diagrams, which show all possible relations between different sets, the Euler diagram shows only relevant relationships…”
