Add a visualisation to the language family visualisation tool that shows the development of all bilingual dictionaries involving the language over time (i.e., how many stems in each dictionary starting from when it was created up to the present). Sample data will be provided by the mentor. This graph should go in the bottom-left pane of the visualisation; if another graph is already there when you work on this task, make a switch to toggle between the two visualisations.
For further information and guidance on this task, you are encouraged to come to our IRC channel.
