Pick a day and an inclusive first / last hour (if last is earlier than first, the range wraps over midnight). Flows are drawn straight between area centers (district or sub-district). Moving dots share one trips-per-dot scale on every link (default Auto) so flows are comparable—see controls and the note under the map. Dot speed reflects how busy the link is and how long the hop is. All trip counts use trip start time within your chosen hours.
