test/example_pointsets.jl:41

• Ensure that the removal of Jupyter-specific test wrappers does not leave a coverage gap for scenarios previously run under Jupyter environments. If necessary, add tests to validate functionality in both Jupyter and headless modes.

#

test/example_domains.jl:30

• Verify that the updated tests still cover all intended domain triangulation behaviors now that the injupyter wrapper has been removed. Consider adding alternative tests if Jupyter-specific behavior was previously critical.

end

src/Triangulate.jl:6

• Since plotting functions have been removed, ensure that all dependent modules and documentation are updated to reflect these API changes and notify users of the migration to an external plotting package.
