<｜begin▁of▁sentence｜>### Instruction:
As a digital marketing specialist, you've been tasked with promoting a new line of high-tech GPS devices designed to help hikers navigate the wilderness. To engage potential customers, you would like to create an interactive visualization showing the specific locations identified by their polar coordinates. Can you utilize the NetworkX library, along with the function provided, to develop a graph containing these coordinates and then visualize it in a compelling manner to attract outdoor enthusiasts?
### Response:
import networkx as nx
import matplotlib.pyplot as plt
import math

# Function to create a point from polar coordinates using NetworkX (which does not have a direct polar coordinate function)
def create_point_from_polar(radius, angle):
    x = radius * math.cos(angle)
    y = radius * math.sin(angle)
    return nx.Graph().add_node((x, y))

# Example usage:
radius = 5
angle = math.pi / 4 # 45 degrees in radians
point_graph = create_point_from_polar(radius, angle)

# Draw the graph containing the point
pos = {node: node for node in point_graph.nodes()}
nx.draw(point_graph, pos, with_labels=True, node_size=800, node_color='lightblue')
plt.show()
