 * Range bar carries `[start, end]` per point. The columns are named start and end rather
 * than min and max on purpose: `RangeBarValueType` gives no ordering guarantee, so a
 * series may legitimately have a start above its end.
 *
 * Its `valueFormatter` receives the whole tuple and returns one string, so there is a
 * single formatted column rather than one per bound.
