“Let’s Speak Out” is the title of my book. This book introduces the endangered languages of various countries in Canada. The book contains a large number of data visualization designs to assist in explaining the status of these endangered languages. In the process of designing this book, I also used the collected data to curate an exhibition of “Canadian Endangered Languages” (the small picture in the lower right of the window), which more intuitively reflects the situation of language disappearance, and calls on everyone to join in the protection of endangered languages. language in action.
