The same thing can be done with the chords:
D - E---2----  Dsus2 E--0---  Dsus4 E---3--|
    B---3----        B--3---        B---3--|
    G---2----        G--2---        G---2--|
    D---0----        D--0---        D---0--|

Played D, Dsus2, D, Dsus4 - you cn always change the rhythm to suit your style :D
