1. A method, comprising: initializing, using a processor, a layered overview visualization of a computing environment having a plurality of elements, said elements comprising assets or groups of assets in the computing environment, said initializing comprising: defining a plurality of hierarchical levels including a first level and a second level below the first level; assigning a first element of the plurality of elements and a second element of the plurality of elements to the first level; and assigning a common element to the second level, wherein the common element is included within both the first element and the second element in the first level; and identifying an overlap between the first element and the second element of the first level as a result of the presence of the common element in the second level that is included in both the first element and the second element of the first level; and navigating the layered overview visualization, said navigating comprising: receiving a selection of a view of the computing environment; receiving a selection of the first level of the hierarchical levels within the selected view; receiving a selection of the overlap of the first element and the second element in the selected level and highlighting the overlapping elements; and displaying on a screen the selected level and the highlighted overlapping elements in the selected level.
