Force-Directed Layout oct-tree

Classes

class helios.layouts.force_directed.HeliosFr(edges, network_draw, viscosity=0.3, a=0.0006, b=1, max_workers=8, update_interval_workers=0, velocities=None)[source]

A 2D/3D Force-directed layout method

This method is a wrapper for the helios force-directed algorithm, heliosFR. HeliosFr is a force-directed layout algorithm that is based on oct-trees. The algorithm is designed to work with a large number of nodes and edges.

Parameters

  • edges (ndarray) –

  • network_draw (NetworkDraw) –

  • viscosity (float, optional) –

  • a (float, optional) –

  • b (float, optional) –

  • max_workers (int, optional) – number of threads

  • update_interval_workers (float, optional) – When you set this to a value greater than zero the helios-fr will wait to perform each step. This can be used to reduce the CPU consumption
