/**
* A bar chart (see http://code.google.com/apis/chart/#bar_charts).
*
* @binding data the array, or array of arrays, of data
* @binding size "wxh" format chart size ("300x400")
* @binding width the width of the chart
* @binding height the height of the chart
* @binding colors an array of color values (for lines, bars, pie slices)
* @binding title the title of the chart
* @binding titleColor the color of the chart title
* @binding titleSize the size of the chart title
* @binding backgroundStyle "solid", "gradient", or "stripes"
* @binding background the solid color of the background
* @binding transparency the transparency color of the chart background
* @binding legend an array of legend values
* @binding labeledAxes an array of axes that have labels ("x,y,r") (see http://code.google.com/apis/chart/#multiple_axes_labels)
* @binding axisLabels an array of array of axis labels
* @binding custom custom query string parameters to append
* @binding id the id of the img tag
* @binding class the class of the img tag
* @binding alt the alt text of the img tag
* @binding encoding the explicit chart encoding to use ("simple", "extended", "text")
* @binding normalize if true, values will be normalized relative to the max value
* @binding maxValue if false, normalization is off or set to a number to override the max value
* @binding scaling if true, numbers will be scaled with an automatic min/max, or set to min/max string values (see http://code.google.com/apis/chart/#data_scaling)
* @binding fillArea the fill area (see http://code.google.com/apis/chart/#fill_area_marker)
* @binding lineStyles the line styles (see http://code.google.com/apis/chart/#line_styles)

* @binding shapeMarkers the string that specifies shape markers (see http://code.google.com/apis/chart/#shape_markers2)
* @binding gridLines the override for specifying all gridline values (see http://code.google.com/apis/chart/#grid)
* @binding gridXStep the number of steps on the x axis between grid lines
* @binding gridYStep the number of steps on the y axis between grid lines
* @binding gridLineSize the number of pixels in the line of the dash part of the grid line
* @binding gridBlankSize the numer of pixels in the spacing between dashes in the grid line
* @binding orientation "horizontal" or "vertical" orientation
* @binding barWidth the width of the bars of the graph
* @binding spacing the spacing between bars
* @binding groupSpacing the spacing between groupds of bars
