However, layering software is organized as if the user is looking through two or more overlays that are clear except for their graphic information.  Layering of clickable graphics originated as "HyperMedia" in the early 1990s with HyperCard and Supercard on the Macintosh computer.  Graphics programs such as SuperPaint, then Photoshop also provided layers for creating graphics.

With the advent of the World Wide Web, graphics could be sent over the Internet.  The HyperMap Atlas takes advantage of the ability to layer these graphics to create a rich Web page experience.  Its graphics are "smart."  In response to user-clicks, the software causes graphics to be inserted into slots of various sizes to provide changeable map overlays, key symbols, and layered pop-up annotations.  The purpose is to provide smooth, uninterupted interactivity to support a flowing analytical thought process.
