dArc

Could you specify which dArc you have in mind? The term dArc is used in different contexts (for example as an acronym for various projects or concepts in software, mathematics, or design). If you can name the particular project, organization, or domain, I can generate a concise, neutral wiki-style article tailored to that specific "dArc." If you’d like, I can also provide a generic disambiguation-style article that outlines the different uses of the term without favoring any single one.
