1. A computer implemented method for depicting relationships between a plurality of real-world objects having a plurality of attributes using a preview layer created using attribute information that identifies a plurality of attributes for each of the plurality of real-world objects, the preview layer including a first indicia that identifies a first attribute of the plurality of attributes as well as real-world objects that exhibit the first attribute and a second indicia that identifies a second attribute of the plurality of attributes as well as real-world objects that exhibit the second attribute, the preview layer being created without first filtering the attribute information, the method comprising: receiving search criteria that identifies an attribute of the plurality of attributes; forming a search query that includes the attribute from the search criteria; modifying the preview layer to include additional indicia that identifies the attribute from the search criteria as well as real-world objects exhibiting that attribute; overlaying the modified preview layer on top of a corresponding base map; and displaying the modified map image on a display device.
