Simple algorithm, just look for the next backward jump that points to
before the cursor.
Then draw an arrow connecting the jump to its target.
Do this as you move the cursor, entering/exiting possible loops.
Ex (graph chars replaced to avoid mail encoding woes):
avc_has_perm_flags
0.00 | nopl 0x0(%rax)
5.36 |+-> 68: mov (%rax),%rax
5.15 || test %rax,%rax
0.00 || v je 130
2.96 || 74: cmp -0x20(%rax),%ebx
47.38 || lea -0x20(%rax),%rcx
0.28 || ^ jne 68
3.16 || cmp -0x18(%rax),%dx
0.00 |+------^ jne 68
4.92 | cmp 0x4(%rcx),%r13d
0.00 | v jne 68
