   The _vennplot_ package enables the user to plot Venn diagram for any
logical relation.  Logical atoms are represented as equally distanced
circles of different random colours which help in distinguishing
different circles.

   No known bug, but in case some issue needs to be addressed, please
share it on Maxima mailing list.
