Well, Gijs suggested using wld files to connect simple raster images to
your map (see below). The wld files georeference your raster images. (See
http://mesonet.agron.iastate.edu/docs/radmapserver/howto-3.html#ss3.3 for
an example and explanation).

So, if I understand correctly you would have to create one raster and one
wld file for every entity for which you need a chart. Then you can include
them in your map file just like any other maps.
