A story map of every official place name in Canada

A new #30DayMapChallenge page draws Canada's official place names as a story map, stepping through history by the date each name was approved.

• unmap.dev/30daymapchallenge/6 draws every name in the Canadian Geographical Names Database that carries an official decision date: all 365,649 of them.
• A card steps through seven chapters, from the names approved before the Geographic Board existed in 1897 to a slider that lets you pick any year.
• Each dot is coloured by the year its name became official, so eras of heavy naming activity stand out at a glance.
