  We consider the flip-width of geometric graphs, a notion of graph width
recently introduced by Toru\'nczyk. We prove that many different types of
geometric graphs have unbounded flip-width. These include interval graphs,
permutation graphs, circle graphs, intersection graphs of axis-aligned line
segments or axis-aligned unit squares, unit distance graphs, unit disk graphs,
visibility graphs of simple polygons, $\beta$-skeletons, 4-polytopes, rectangle
of influence graphs, and 3d Delaunay triangulations.
