tags must start with a letter; if they look like integers, they're
interpreted as item handles.

:::

as for the attribute error, your code snippet doesn't show how or
where you're setting the "canvas" attribute, or what you're setting
it to.  Python usually tells you what attribute it expected; if it com-
plains about a missing "canvas", make sure it's set.  if it complains
about a missing "coords", make sure you set it to a canvas widget.
if you cannot sort it out yourself, post more code, and include the
full traceback.
