Slider<D> class
Chart behavior that adds a slider widget to a chart. When the slider is dropped after drag, it will report its domain position and nearest datum value. This behavior only supports charts that use continuous scales.
Input event types: tapAndDrag - Mouse/Touch on the handle and drag across the chart. pressHold - Mouse/Touch on the handle and drag across the chart instead of panning. longPressHold - Mouse/Touch for a while on the handle, then drag across the data.
