why dot file is generated rather jpg file in Ruby Graph Library (RGL)?

I have written the following code. When I run this file graph.dot file is generated rather than graph.jpg. I can't understand why so. Does any body have any idea?

My code is as:
require 'rgl/adjacency'
require 'rgl/dot'
dg=RGL::DirectedAdjacencyGraph[1,2,2,3,2,4,4,5,6,4,1,6]
dg.write_to_graphic_file('jpg')

RGL uses dot files as an intermediary format to produce image formats, it doesn't produce them itself. That is why you are seeing a graph.dot file.

If you have a dot binary available (part of the GraphViz package), rgl will invoke it to produce a graph.jpg file.

You can download the GraphViz package at the project homepage, or use homebrew (if you're on a mac) to install it with brew install graphviz.
