A technique is provided for generating, resizing and rescaling an image. The image may be of a physical system, and may be based upon data collected from components via a data network. Elements in the image are associated into logical groups. The image is displayed in a display area, the dimensions of which may be changed by a user. Upon a change in a first dimension of the display area, the image is rescaled so as to maintain an original aspect ratio of the image. Resizing of the display area in a second direction does not rescale the image, but changes the number of logical groups displayed.
