34+ The TkAgg interactive backend also typically works out of the box.
35+ It requires Tk bindings, which are usually provided via the Python
36+ standard library's ``tkinter `` module. On some OSes, you may need
37+ to install a separate package like ``python3-tk `` to add this
38+ component of the standard library.

41+ python-build-standalone project, which only gained usable Tk
42+ bindings recently (August 2025). If you are having trouble with the
43+ TkAgg backend, ensure you have an up-to-date build, e.g. ``uv self
44+ update && uv python upgrade --reinstall ``.
