r"""
Returns a bull graph with 5 nodes.
A bull graph is named for its shape. It's a triangle with horns.
This constructor depends on `NetworkX <http://networkx.lanl.gov>`_
numeric labeling. For more information, see this
:wikipedia:`Wikipedia article on the bull graph <Bull_graph>`.
PLOTTING:
Upon construction, the position dictionary is filled to
override the spring-layout algorithm. By convention, the bull graph
is drawn as a triangle with the first node (0) on the bottom. The
second and third nodes (1 and 2) complete the triangle. Node 3 is
the horn connected to 1 and node 4 is the horn connected to node
2.
ALGORITHM:
Uses `NetworkX <http://networkx.lanl.gov>`_.
EXAMPLES:
Construct and show a bull graph::
sage: g = graphs.BullGraph(); g
Bull graph: Graph on 5 vertices
sage: g.show() # long time
The bull graph has 5 vertices and 5 edges. Its radius is 2, its
diameter 3, and its girth 3. The bull graph is planar with chromatic
number 3 and chromatic index also 3. ::
sage: g.order(); g.size()
5
5
sage: g.radius(); g.diameter(); g.girth()
2
3
3
sage: g.chromatic_number()
3
The bull graph has chromatic polynomial `x(x - 2)(x - 1)^3` and
Tutte polynomial `x^4 + x^3 + x^2 y`. Its characteristic polynomial
is `x(x^2 - x - 3)(x^2 + x - 1)`, which follows from the definition of
characteristic polynomials for graphs, i.e. `\det(xI - A)`, where
`x` is a variable, `A` the adjacency matrix of the graph, and `I`
the identity matrix of the same dimensions as `A`. ::
sage: chrompoly = g.chromatic_polynomial()
sage: bool(expand(x * (x - 2) * (x - 1)^3) == chrompoly)
