<｜begin▁of▁sentence｜>### Instruction:
As an agronomist, you are studying and managing an agricultural system using network analysis. Suppose you have a network of 5 interconnected fields, and each field is connected to 2 other fields. You want to represent this network visually but without displaying the individual shapes of the fields. In this case, you want to use the NullDrawer from the network analysis tool to override the default shape of the fields and ensure that no specific shapes are drawn in the output plot.
### Response:
from igraph import Graph, plot
from igraph.drawing.shapes import NullDrawer

g = Graph.Tree(5, 2)
visual_style = {'vertex_shape': [NullDrawer()]*5}
plot(g, **visual_style)
