It enables us to create interactive plots interactively on IRuby notebook, a web-based Ruby environment. Nyaplot is totally web-based gem and plots can be embedded into Rails or Sinatra seemlesly. Supported charts include basic 2D plot, 3D plot, Map plot and plot for Biology. See nbviewer (http://nbviewer.ipython.org/github/domitry/nyaplot/blob/master/examples/notebook/Index.ipynb) to overview what plots can be created with nyaplot and how to do it.}

   U

Thank you for installing Nyaplot gem.

We strongly recommend you to install IRuby, an interactive
Ruby environment on web browser at the same time.

$ gem install iruby

If you wonder how to use Nyaplot, see /path/to/nyaplot/examples/notebook
and run `iruby notebook` in the directory.
You can find these notebook on your browser:
http://nbviewer.ipython.org/github/domitry/nyaplot/blob/master/examples/notebook/Index.ipynb

You can also use nyaplot without IRuby like /path/to/nyaplot/examples/rb
or on your browser:
https://github.com/domitry/nyaplot/tree/master/examples/rb

Feel free to raise Issue or Pull-request on GitHub.
Most pull-request might be accepted unless it is broken or too destructive.

Enjoy Nyaplot!
