April 20, 2026 - That is, depending on input, eulerr will sometimes produce Venn diagrams but sometimes not. R features several packages that produce Euler diagrams; some of the more prominent ones (on CRAN) are

eulerr generates area-proportional Euler diagrams that display set relationships (intersections, unions, and disjoints) with circles or ellipses.

April 21, 2026 - Resolve a gap option to a numeric in native units inside the current measurement viewport. NULL → falls back to padding_native so the visible leader-tip gap matches the spacing between label and quantity. A grid::unit value converts to native; a bare numeric is interpreted as lines (same convention as eulerr_options()$padding).

eulerr generates area-proportional Euler diagrams that display set relationships (intersections, unions, and disjoints) with circles or ellipses.

Learn R Programming · eulerr (version 7.0.2) Fit Euler diagrams (a generalization of Venn diagrams) using numerical optimization to find exact or approximate solutions to a specification of set relationships. The shape of the diagram may be a circle or an ellipse.

eulerr generates area-proportional Euler diagrams that display set relationships (intersections, unions, and disjoints) with circles or ellipses.

Defaults for these values, as well ... using eulerr_options(). If the diagram has been fit using the data.frame or matrix methods and using the by argument, the plot area will be split into panels for each combination of the one to two factors. For users who are looking to plot their diagram using another package, all the necessary parameters can be collected if the result of this function ...

To tackle this, we use a SKYLINE-BL rectangle packing algorithm (Jylänki 2010) designed specifically for eulerr.

April 21, 2026 - In our example, the diagError is r fit2$diag_error and our stress is r fit2$stress, suggesting that the fit is accurate. We can now be confident that eulerr provides a reasonable representation of our input using circles. Were it otherwise, we might try to use ellipses instead.
