The number of students who have participated in at least one course during the selected year will be made available for each country at the endpoint /api/v1/partners/{partner_id}/dashboard/students.

When zooming in, if the cities are visible on the map, the number of students for each city will be made available.

When zooming in even more, if there is enough space on the map to show the locations of each organization's centers within the cities' areas, the number of students for each center will be made available.

If the view mode is set to All MWB participants, the endpoint will be /api/v1/partners/dashboard/students.
