# = First example
# This is the ruby version of "Getting Started" example of Protovis introduction.
# On this example we show you how can you build a bar chart using panel and bar marks.
# A mark represents a set of graphical elements that share data and visual encodings. Although marks are simple by themselves, you can combine them in interesting ways to make rich, interactive visualizations
