Method appendSeries

src/data/createDataStore.ts:19–19

* Appends new points to an existing series without re-uploading the entire buffer when possible. * * - Reuses the same geometric growth policy as `setSeries`. * - When no reallocation is needed, writes only the appended byte range via `queue.writeBuffer(...)`. * - Maintains `pointCount`

(index: number, newPoints: ReadonlyArray<DataPoint>)

   * Throws if the series has not been set yet.
