/**
 * 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.
