+Grandalf is a python package made for experimentations with graphs and drawing
+algorithms. It is written in pure python, and implements two layouts: the
+Sugiyama hierarchical layout and the force-driven or energy minimization
+approach. While not as fast or featured as _graphviz_ or other libraries like
+_OGDF_ (C++), _GDToolkit_ (C), _tulip_ (Java), it provides a way to draw and
+navigate graphs no larger than thousands of nodes, while keeping the source code
+simple enough to make it possible to easily tweak and hack any part of it for
+experimental purpose. With a total of about 1500 lines of python, the code
+involved in drawing the Sugiyama (dot) layout fits in less than 600 lines.
+The energy minimization approach is comprised of only 250 lines!
+
+Grandalf does only two not-so-simple things:
+* computing the nodes (x,y) coordinates (based on provided nodes dimensions, and
+ a chosen layout)
+* routing the edges with lines or nurbs
