* Geographic maps (see http://code.google.com/apis/chart/#maps).
*
* @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 (default color followed by gradient colors)
* @binding backgroundStyle "solid", "gradient", or "stripes"
* @binding background the solid color of the background
* @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 area the geographic area to show ("africa", "asia", "europe", "middle_east", "south_america", "usa", "world")
* @binding regions the regions to color
