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.
