<｜begin▁of▁sentence｜>### Instruction:
Imagine you are channeling the flow of Universal energy into a representation of connections between two pivotal energy centers. In the process, you're aiming to document this unique energetic exchange in a format that is universally recognizable, much like a sacred diagram or mandala. 

Specifically, you have two primary points, one named 'A' symbolizing perhaps the crown chakra, and another named 'B' representing the root chakra. Energy flows in one direction in this instance, from 'A' to 'B', and this flow carries its own identity, known as 'A to B'. 

How would you transcribe this symbolic, energetic pathway onto a Graphviz dot file, ensuring that this intentional mapping of energy from one center to the next is preserved for others to observe, study, and understand? Reflect upon the GML file, if one exists, and consider how the data of this energetic transaction could be integrated into such a scenario.
### Response:
import networkx as nx

# Create a new graph
G = nx.DiGraph()

# Add nodes with the node attribute 'label'
G.add_node(1, label='A')
G.add_node(2, label='B')

# Add edge with the edge attribute 'label'
G.add_edge(1, 2, label='A to B')

# Write to a dot file
nx.nx_pydot.write_dot(G, 'my_graph.dot')
