A clear and concise description of what the bug is.

I customized a component yh_color_table，but it was wrong,I don't know what's wrong？
error: "'yh_color_table'"
stacktrace: "Traceback (most recent call last):↵ File "/data/app/superset-web/superset/views/base.py", line 135, in wraps↵ return f(self, *args, **kwargs)↵ File "/data/app/superset-web/superset/utils/decorators.py", line 63, in wrapper↵ check_perms(*args, **kwargs)↵ File "/data/app/superset-web/superset/views/core.py", line 125, in check_datasource_perms↵ force=False,↵ File "/data/app/superset-web/superset/views/utils.py", line 120, in get_viz↵ viz_obj = viz.viz_types[viz_type](↵KeyError: 'yh_color_table'↵")

Ping gave me some suggestions on how to create a custom component？

do you mind updating the title to be more human readable? did you build it using dynamically imported viz plugins? @lcyh
