If your application requires a geographic map as a background, you can install a map renderer that uses the Rogue Wave® JViews Maps facilities to read map formats—vector or raster—and to display nodes according to their latitude and longitude.

You can instead add a vector or a bitmap background that is not a map. You can use Composer, a graphics editor provided with JViews Diagrammer, to draw your vector background. Composer saves to the JViews proprietary IVL format or to SVG format. Other authoring tools that create bitmaps or SVG images can also be used.
