Graphviz

From $1

This library contains functions for generating graphs. See attached files for documentation on the graph notation.  関連リンク: Extension Overview, DekiScript Overview, Extension Demos.

Assembly: mindtouch.deki.services
SID: http://services.mindtouch.com/deki/d...07/06/graphviz

Configuration:

Before the Graphviz service can be used, it must be configured with the locations of the required Graphviz applications.  Graphviz applications can be downloaded here.  VM users with SSH access can simply type apt-get install graphviz (paths are all prefixed with /usr/bin/: e.g., /usr/bin/dot, /usr/bin/neato, etc.).

Config Key Description
dot-path Path to dot application.
neato-path Path to neato application.
twopi-path Path to twopi application
circo-path Path to circo application.

Functions:
  1. graphviz.circo
  2. graphviz.dot
  3. graphviz.neato
  4. graphviz.twopi

graphviz.circo(graph : str) : uri

Parameters:

Name Type Description
graph
str
Graph description.

Samples:


Output

To generate a simple "Hello World" graph using CIRCO layout: 

{{ graphviz.circo("digraph G { Hello -> World }") }}
