	 *     If `false` is set, all of interactions (showing/hiding tooltip, selection, mouse events, etc) will be disabled.
	 * @property {boolean} [interaction.brighten=true] Make brighter for the selected area (ex. 'pie' type data selected area)
	 * @property {boolean} [interaction.inputType.mouse=true] enable or disable mouse interaction
	 * @property {boolean} [interaction.inputType.touch=true] enable or disable  touch interaction
	 * @property {boolean|number} [interaction.inputType.touch.preventDefault=false] enable or disable to call event.preventDefault on touchstart & touchmove event. It's usually used to prevent document scrolling.
