Big Faceless Graph Library 2.3.4 (Default branch)
04-21-2008
The Big Faceless Graph Library is a Java class library for creating graphs and charts. It is backed by a full 3D engine, allowing you to create shaded 3D pie, bar, and line graphs as GIF, PDF, PNG, or other image formats. Its features include transparent backgrounds, extensible axes to graph dates, currencies, custom fonts, and spline curve fitting. It is small, fast, and easy to use.

Graph::Reader::Dot(3pm) User Contributed Perl Documentation Graph::Reader::Dot(3pm) NAME
Graph::Reader::Dot - class for reading a Graph instance from Dot format SYNOPSIS
use Graph::Reader::Dot; use Graph; $reader = Graph::Reader::Dot->new(); $graph = $reader->read_graph('mygraph.dot'); DESCRIPTION
Graph::Reader::Dot is a class for reading in a directed graph in the file format used by the dot tool (part of the AT+T graphviz package). Graph::Reader::Dot is a subclass of Graph::Reader, which defines the generic interface for Graph reader classes. METHODS AND CONFIGURATION
"new()" Constructor - generate a new reader instance. $reader = Graph::Reader::Dot->new(); This doesn't take any arguments. "read_graph()" Read a graph from a file: $graph = $reader->read_graph( $file ); The $file argument can be either a filename or a filehandle of a previously opened file. $Graph::Reader::Dot::UseNodeAttr Controls, if implicit node attributes given by the dot directive "node[]" will be merged into (new) nodes. Setting it to 0 or "undef" (default) will not disable this feature. Setting it to any other value will enable this feature. $Graph::Reader::Dot::UseEdgeAttr Controls, if implicit edge attributes given by the dot directive "edge[]" will be merged into edges. Setting it to 0 or "undef" (default) will not disable this feature. Setting it to any other value will enable this feature. RESTRICTIONS
o Default (graph) attributes in subgraphs (i.e. inside "{}") are not processed. o Sub nodes as used by dot's "record" node shape are supported. o Undirected graphs will be treated as directed graphs. This means that the "--" edge operator works as the "->" edge operator. o Be aware that you are loosing scope information on writing back the graph. o Multiple "node[]" or "edge[]" statements in the same scope are not correctly supported.
