A processing device and method may be provided for displaying a graph, including a number of icons. The icons may be thumbnail images of data elements of a data set. A position of the icons may indicate one or more attribute values of an associated set of attributes. A zooming-in operation may cause at least a portion of the displayed graph to be enlarged, such that at least some of the icons may be presented as enlarged, higher-resolution images. A zooming-out operation may cause the presented enlarged images to be reduced in size and presented in a context of the displayed graph. The enlarged images may include at least one selectable link. In some embodiments, when a displayed image, corresponding to an icon, is enlarged beyond a predetermined amount, the displayed image may be replaced by a corresponding data element of the data set.
