# DotR

DotR is a tiny ruby library that makes it easy to construct directed

graphs in a variety of graphic formats using the 'dot' utility from

the Graphviz suite of programs.

In order to use DotR you must have Graphviz installed.

See http://www.graphviz.org for installation instructions and examples

of the output that is possible.

For more information or to contact author Steve Purcell,

please visit http://dotr.sanityinc.com.

## Example

```ruby

d = DotR::Digraph.new do |g|

  g.node('node1') do |n|

    n.label = "MyLabel"

    n.fontsize="8"

  end

  g.node('node2', :label => 'SecondNode') do |n|

    n.connection('node1', :label => 'relates to')

  end

end

File.open('diagram.png', 'w') { |f| f.write(d.diagram(:png)) }

```
