A rhythm chart is like a lead sheet without the lyrics or vocal lines. By taking the vocal lines out of the staff, there is more room to indicate unique rhythmic notations that are beneficial for guitar, bass and drums. Generally, these players are not singing with the band, so the vocal lines are not necessary. The advantage of a rhythm chart over a chord chart is that there is more detailed information about the song map and the exact rhythms of the chord progressions.
