NotImplementedError when running examples/demo/updating_plot/updating_plot1.py

[homosapien-lcy]

Problem Description When running examples/demo/updating_plot/updating_plot1.py, a NotImplementedError will be raised. It seems that this error comes from enable/enable/examples/_example_support.py and the _create_component is left unimplemented. If this is deliberately left unimplemented then no fix is needed.

Reproduction Steps:

python  examples/demo/updating_plot/updating_plot1.py
