/**
* ErrorBar renders whiskers to represent error margins on a chart.
*
* It must be a child of a graphical element.
*
* ErrorBar expects data in one of the following forms:
* - Symmetric error bars: a single error value representing both lower and upper bounds.
* - Asymmetric error bars: an array of two values representing lower and upper bounds separately. First value is the lower bound, second value is the upper bound.
*
* The values provided are relative to the main data value.
* For example, if the main data value is 10 and the error value is 2,
* the error bar will extend from 8 to 12 for symmetric error bars.
*
* In other words, what ErrorBar will render is:
* - For symmetric error bars: [value - errorVal, value + errorVal]
* - For asymmetric error bars: [value - errorVal[0], value + errorVal[1]]
*
* In stacked or ranged Bar charts, ErrorBar will use the higher data value
* as the reference point for calculating the error bar positions.
