Plotting a List of Vectors?

Questions
1

Greetings,

I realize this must be easy, but how does one plot a list of (real) vectors, e.g. {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}?

Thanks,

Dear Dean,

What does {1,2,3} represent here? should the vector start at {0,0,0} and point to {1,2,3} ? Where does the vector {4,5,6} start? also at {0,0,0} ?

vec = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
Graphics3D[Arrow[{{0, 0, 0}, #} & /@ vec]]

I’m not sure if you want this exactly.

Regards.

Thank you. That’s exactly what I needed. As a future mathematician, I should have been more specific.
