Drawing methods for lattices are reviewed in

  M. Mueller-Hannemann: Drawing trees, series-parallel digraphs and lattices.
  Chapter 3 of Wagner/Kaufmann (eds.): Drawing Graphs - Methods and Models.
  Lecture Notes in Computer Science vol. 2025.
  Springer, 2001.

There is a system called TOSCANA for visualizing (concept) lattices; see

  http://www.mathematik.tu-darmstadt.de/ags/ag1/Software/Toscana/Welcome_en.html

For more recent developments, you may want to contact Richard Cole
from the University of Queensland, Australia.  Chapter 4 of his PhD
thesis is on "Automated Layout of Concept Lattices"; go to

Enjoy,
