+Subject: [PATCH 1/3] Adapt `PointGraph.remove()` for Pandas 3
+
+With Copy-on-Write (PDEP-7) behavior in Pandas 3, the edges property
+getter returns a read-only ndarray, so we cannot use the `-=` operator
+on it.

+Subject: [PATCH 2/3] In `test_set_properties`, avoid `LossySetitemError`
+
+Since Pandas 3 checks for narrowing (potentially lossy) type
+conversions, be more explicit about data types of random test data
+ndarrays and/or do narrowing conversions on them explicitly in the test
+before checking that their values round-trip.
