DF does not show swap partition

I am using DF to check disk usage and partition. Why isn't it showing my swap partition? I have 8GB to share when I installed CentOS 7.

root@localhost abigail]# df -h
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/centos-root  196G   30G  166G  16% /

Swap is not a filesystem (like ext3) and therefore is not mountable in the usual sense. Use "swapon -s", it will validate digits from the "free" output.
