eulerr vs TLF-Library: at a glance
What is eulerr?
The area-proportional Euler diagram package is finished software, and maintained like it.
eulerr generates area-proportional Euler and Venn diagrams by numerically optimizing shape positions and sizes to match set relationships, with the fitting done in C++. The last feature release was 7.0.0 in December 2022, which made the optimization's loss function user-selectable. Everything since has been maintenance: documentation URL corrections, a strip-layout fix when grouping, an Armadillo deprecation, and an R CMD check warning about an unignored config file.
What is TLF-Library?
The Open Systems Pharmacology plotting layer spent 2025 absorbing a ggplot2 major break.
tlf is the plotting library behind Open Systems Pharmacology's tables, listings and figures — a ggplot2 wrapper producing the PK/PD reporting output the OSP suite generates. Recent work splits into two strands: a feature set adding Lower Limit Of Quantification annotation to time-profile and observed-vs-predicted plots alongside a reworked axis-limits API, and then hot fixes to survive ggplot2 v4.0.0's breaking changes. The axis change is the substantive one, separating cropping the view from filtering the data behind it.

The area-proportional Euler diagram package is finished software, and maintained like it.
◆ Current state
eulerr generates area-proportional Euler and Venn diagrams by numerically optimizing shape positions and sizes to match set relationships, with the fitting done in C++. The last feature release was 7.0.0 in December 2022, which made the optimization's loss function user-selectable. Everything since has been maintenance: documentation URL corrections, a strip-layout fix when grouping, an Armadillo deprecation, and an R CMD check warning about an unignored config file.
◆ Where it's heading
This is a mature package whose problem is solved, and the release pattern reflects that — three of the last four releases changed nothing a user would see. What activity remains is tracking its dependencies rather than its own roadmap: keeping up with Armadillo's deprecations and R CMD check policy is the whole of recent work. The two September 2025 releases an hour apart are a fix and its follow-up, not a development cycle restarting.
◆ Prediction
The pattern points to continued upkeep triggered by upstream C++ and CRAN check changes rather than new capability. If anything does move, the configurable loss function added in 7.0.0 is the surface with room left in it.
TLF-Library
0.0ANALYTICS
The Open Systems Pharmacology plotting layer spent 2025 absorbing a ggplot2 major break.
◆ Current state
tlf is the plotting library behind Open Systems Pharmacology's tables, listings and figures — a ggplot2 wrapper producing the PK/PD reporting output the OSP suite generates. Recent work splits into two strands: a feature set adding Lower Limit Of Quantification annotation to time-profile and observed-vs-predicted plots alongside a reworked axis-limits API, and then hot fixes to survive ggplot2 v4.0.0's breaking changes. The axis change is the substantive one, separating cropping the view from filtering the data behind it.
◆ Where it's heading
The library is maturing into a stable reporting dependency rather than growing new plot types — the newest releases are watermark placement, log-tick safety and upstream compatibility, not new figures. Its exposure is to ggplot2: v4.0.0 required same-day hot fixes, which is the risk profile of a wrapper this thin. Note that this feed's version numbers and publication stamps disagree, with 1.5.170 stamped four months before the lower-numbered 1.5.158, so the release order has to be read from version numbers and the changelog ranges rather than from the feed order.
◆ Prediction
With the ggplot2 v4 fallout patched and the LLOQ work promoted to a stable 1.6 line, the next releases most likely continue as small rendering fixes. Nothing in these entries points to a new plot class in progress.
