#Description

GraPy is a simple library that makes it easy for users to create interactive force directed graphs.

Features:

• Utilises PyGame to allow user customisable draw functions for all aspects of the visualisation.
• Visualisations feature a panning the camera and ability to drag nodes by default.
• Users can poll for mouse events and node clicks to implement custom behaviours.
• Visualisation runs in separate thread allowing changes to the graph to be displayed in realtime.
• Use library without installing on target system. Just copy directory and run. (installation information)

#Usage Overview

GraPy models a directed graph using a Graph which contains a collection of Node objects. Graphs are drawn using a Grapher object which handles physics, drawing and mouse input.

#Installation

For a guide to performing either type of installation, view the readme.

Standard Installation:

GraPy can be installed directly to a system using setuptools, and imported using import grapy.

Use Without Installing:

In cases where it is easier not to install GraPy to the system (for example, bundling the library with a project, or on a system where the user does not have installation rights), the library can be used simply by copying the grapy directory to the desired location.
