# = First example (Protovis API)
# This is the protovis API version of "Getting Started" example of Protovis introduction.
# On this example we 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
