Is there an easy way to make tikz picture from sage poset? How about
"prettyprinting" poset that can also be seen as lattice?
To give concrete example:
Poset(([0,1,2,3,4,5,6,7,8], [[0, 1], [0, 2], [0, 3], [0, 4], [0, 6], [0, 7],
[1, 5], [2, 5], [3, 5], [4, 5], [5, 8], [6, 8], [7, 8]])).show()
Poset(([0,2,3,4,5,6,7,8], [[0, 2], [0, 3], [0, 4], [0, 6], [0, 7], [2, 5], [3,
5], [4, 5], [5, 8], [6, 8], [7, 8]])).show()
Second one seems quite good. But in first arrows 0->6 and 4->5
crossed; that could be avoided by moving nodes 6 and 7 are to right.
And then, is there automatic or semi-automatic way to convert
lattice/poset/graph to tikz picture?
Or to handle both at once: program that takes output of .cover_relations
as input and .tex -code as output.
