Error message says "Cannot plot polytopes of dimension larger than 2", but can't plot dimension 1 aswell about polytope HOT 2 CLOSED

Thank you for reporting this. The Exception is raised at:

Following the changes of the code in the past, the test of dimension != 2, and the message have been essentially unchanged since this code was introduced (the message has changed by removing a whitespace character), in tulip: tulip-control/tulip-control@85a9ef3#diff-a3402e018e75772f98fab2fad2a90be9bb565a04576ec077b6e5f5aebb5d89beR94-R96

Initially, this check printed a message and returned early from the call. Later, printing changed to logging, and logging to raising an exception (this change was in 8407888).

Regarding possibilities for change, the existing implementation of the function polytope.polytope._get_patch passes the polytope vertices to the constructor of the class matplotlib.patches.Polygon:

The docstring of the class matplotlib.patches.Polygon requires two-dimensional points:

So with the current implementation, plotting one-dimensional polytopes is not supported. If this is ever implemented, some convention would be needed, e.g., that one-dimensional polytopes are plotted on the x-axis. Until then, the proposed change of replacing the word "larger" with "other" appears to be a good choice.

This issue applies also to the analogous test and message about regions (a class that can represent polytopes that can be nonconvex):

Addressed in commit ed6e798, which is now included in the mainline branch.
