Thanks @yu0A for working on this!

Please add some tests so we can make sure this works as expected. I think you should test that the intended HTML elements are deleted, that the behavior is idempotent (calling show and destroy multiple times does not break matplotlib), and that it is compatible with pyodideMplTarget.

This very simple test would be a good starting point to take a look.

Also, please

• update the PR title to be a bit more descriptive, we can search for it later.
• update the CHANGELOG.md

Thanks. It seems like CI was failing because of outdated package versions in CI. I updated it in #56, so please merge the main branch in your PR and see if it works.

Thanks!

Released 0.2.2 including this.
