Drawing example

A short description of what the example does.

from knotpy.drawing.draw_matplotlib import draw
from knotpy.notation.native import from_knotpy_notation
import matplotlib.pyplot as plt

Parsing knotpy notation

Load the knot from internal representation.

s = "('OrientedSpatialGraph', {'name': 't0_1(0).0'}, [('Vertex', 'a', (('OutgoingEndpoint', 'b', 0, {'color': 1}), ('OutgoingEndpoint', 'b', 2, {}), ('OutgoingEndpoint', 'b', 1, {})), {}), ('Vertex', 'b', (('IngoingEndpoint', 'a', 0, {'color': 1}), ('IngoingEndpoint', 'a', 2, {}), ('IngoingEndpoint', 'a', 1, {})), {})])"
k = from_knotpy_notation(s)

Perform some operations on the knot.

k.permute_node("a", {0:1,1:2,2:0})

a0i=1 b0o=1
a1i b2o
a2i b1o

Drawing the knot

Draw the know using matplotlib and show it.

draw(k, draw_circles=True, with_labels=True, with_title=True)
plt.show()
