This task is about adding two different graphs on MediaWiki.org for Google Summer of Code and Outreachy programs that show a "Summary of completed projects since YYYY" where YYYY is the year since Wikimedia started participating in each of these programs.

The graph we might need is a bar chart with stacked data series; you can learn how to create such a graph using the Template:Graph:Chart. You might first need an overview of how Templates in general work on wikis.

To count the number of projects completed by interns each year in each of these programs, take a look at the past projects here:
https://www.mediawiki.org/wiki/Google_Summer_of_Code/Past_projects,
https://www.mediawiki.org/wiki/Outreachy/Past_projects. You will be embedding the graphs on the same pages as well!
