isvis

I am sorry, but I cannot find any widely recognized or established information about "isvis" in my knowledge base. It is possible that "isvis" is a very niche term, a misspelling, a proprietary product name, a personal project, or something else entirely that is not part of general public knowledge.

If you could provide more context or details about what "isvis" refers to, I might be able to offer a more helpful response. For example, knowing if it's related to a specific field like technology, biology, art, or a particular company could be beneficial. Without further information, I am unable to generate a wiki-style article.
