<｜begin▁of▁sentence｜>### Instruction:
Given a karate club graph where each node is assigned to a 'club' community, create instances of NodePosition for each node, with coordinates, size, and community label, then arrange them in a list. Each NodePosition instance should include the node's id, its corresponding x and y coordinates based on the node's id, a predefined size for the node, and the community it belongs to (e.g., 'Mr. Hi' or 'Officer').
### Response:
import networkx as nx
from graspologic.layouts import NodePosition

# Sample graph
G = nx.karate_club_graph()

# Define node positions manually
positions = {
  node: NodePosition(node_id=str(node), x=float(node), y=float(node), size=5.0, community=G.nodes[node]['club'])
  for node in G.nodes(data=True)
}

# Convert positions to a list of NodePosition instances
node_positions_list = list(positions.values())

# Now you can use these positions in concert with other visualisation tools in graspologic
