Before revision:  With this in mind, we propose the Zoomable Multilevel Tree (ZMLT) algorithm for  map-like visualization of large graphs that is representative, real, persistent, overlap-free labeled, planar, and compact.
After revision:  With this in mind, we propose the Zoomable Multilevel Tree (ZMLT) algorithm for multi-level tree-based, map-like visualization of large graphs that is representative, real, persistent, overlap-free labeled, planar, and compact.
