Simple D3 modular chart

A very, very simple modular chart based on [Mike Bostock's recommendation](// A very, very simple D3 modular chart based on http://bost.ocks.org/mike/chart/)

Creates a new chart type "histobar" that when insantiated, renders the data as a string in an SVG. Obviously not useful in itself, but the simplest possible reusable chart as a place to start.
