# INTRODUCTION:
#
#  In 2007, Neelakanth Nadgir did post  a script on his blog to display
# ASCII Bar graphs using the Ruby language. To have a quick way to plot
# some numbers on terminal to understand tendencies and quickly visuali
# ze things is very useful. So, as he did published the script  "as-is"
# and as he put on his blog "In the spirit of sharing", I did some chan
# ges on it, and did put it on github to share.  Hope you enjoy!
# 
# Take a look at this Screenshot:
