Is it possible to have a taxonomy archive that lists taxonomy terms?

For example, I have a post type called foo. I can view all posts of type foo at the following url: mysite.com/foo.

I then attach a taxonomy called bar, in which the terms are foobar and foobaz.

I can access the posts assigned the term foobar at mysite.com/bar/foobar. But is it possible to get an archive containing foobar and foobaz at the url mysite.com/bar?

Yes, I am aware that I can just create a page and call wp_list_categories(), but I was looking for an automatic solution that mirrors the post type functionality.

What TheDeadMedic said in the comments. A page would do the trick with a custom template. If you’re not wanting to mix these landing pages with actual pages – the wp-taxonomy-landing plugin/library should do the trick.
