NetworkDiagram

A lightweight Python library for creating Project Network Diagrams (CPM/PERT), calculating paths, and visualizing activity dependencies using NetworkX and Matplotlib.

Features

• Easy Node Management: Add activities with durations and string-based predecessor lists (e.g., "A,B").
• Automatic Pathfinding: Detects all probable paths from Start to End.
• Visualisation: Generates directed graphs with arrows and duration labels using matplotlib.
• CPM Ready: Built on a node structure supporting Probable Paths, Critical Path.

Dependencies

To use the visualization features, you must have the following libraries installed:

• networkx (for graph theory and structure)
• matplotlib (for plotting the diagram)

Installation

pip install networkdiagram

from networkdiagram import CriticalPathMethod

cpm = CriticalPathMethodk()

activities = ['A','B','C','D']
durations = [2,5,4,2]
predecessors = ['-','A','B','B,C']

cpm.add_activity('O',0)
cpm.add_activities_relations(activities,durations,predecessors)
