{vector} is about the typesetting of vector notation, e.g. symbols or row vectors/column vectors. For questions about creating vector graphics in a (La)TeX document, use {diagrams}, or a package specific tag. For questions about including externally created graphics in a document, use {graphics}.

Row and column vectors are often typeset as matrices, and a symbol representing a vector may use \vec for an arrow, be underlined (with \underline), or be made bold with \mathbf.
