MatrixExporter sounds good.  A pattern you might consider instead of
static methods is to support "knob" methods for tweaking the formatting
before the export, e.g.

String generateMatrixWithBrackets(Graph g)
{
    MatrixExporter exporter = new MatrixExporter();
    StringWriter sw = new StringWriter();
    exporter.setBrackets("[","]");
    exporter.exportAdjacencyMatrix(sw, g);
    return sw.toString();
}

Just a made-up example for an exporter which supports bracket
customizatoin.
