The interface describes timeline movement by dragging or using the arrow keys, with spacebar playback; users can also hover over territories or battles and click to open a story. Its map layers draw on sources with distinct coverage, including Chronas for yearly rulers and CHGIS for historical Chinese prefectures. The page also identifies regional differences in its battle-selection thresholds and calls out contested chronology dates for early China.
