<｜begin▁of▁sentence｜>### Instruction:
As an interior decorator, you've been tasked with enhancing the aesthetics and functionality of a client's office space. The client has requested a customized feature for their office's visual representation, which involves creating a custom edge drawer to override the default label position in a graph visualization. The goal is to place the labels at the midpoint of each edge and ensure that they are center-aligned. This customization will contribute to the overall interior design of the office, allowing for a visually appealing and well-organized representation of their network connections.

During the design process, you will need to integrate graph visualization tools like NetworkX to implement the custom edge drawing feature. By employing your expertise in interior design and combining it with technical knowledge of graph visualization libraries, you can create a custom solution that aligns with the client's preferences and the functionality of the office space. This will result in a graph representation that not only reflects the client's taste but also enhances the visual appeal and organization of their network connections within the office environment.
### Response:
import igraph as ig

# Create a simple undirected graph
g = ig.Graph(edges=[(0, 1), (1, 2), (2, 0)])

# Custom edge drawer class inheriting from AbstractEdgeDrawer
class CustomEdgeDrawer(ig.AbstractEdgeDrawer):
    def get_label_position(self, edge, src_vertex, dest_vertex):
        # Here we override the default implementation to customize label positioning
        mid_x = (src_vertex['x'] + dest_vertex['x']) / 2
        mid_y = (src_vertex['y'] + dest_vertex['y']) / 2
        return (mid_x, mid_y), ('center', 'center')

# Assuming we have a layout for our graph
g.vs['x'] = [0, 1, 2]
g.vs['y'] = [0, 1, 0]

# Create an instance of our custom edge drawer
edge_drawer = CustomEdgeDrawer(g)

# Example usage to get label position for an edge
edge_label_pos = edge_drawer.get_label_position(g.es[0], g.vs[g.es[0].source], g.vs[g.es[0].target])
print(edge_label_pos)
