Diagramm über Diagramme in der englischsprachigen Wikipedia: Anzahl der Verwendungen der neuesten Daten des Diagramms in Artikeln nach Jahr (viele Artikel verwenden alte/veraltete Datengrafiken) [OC]

Made this chart after creating and populating https://commons.wikimedia.org/wiki/Category:Charts_by_year_of_latest_data (for over 2 years and it contains most used charts by now) as described on [the file description page](https://commons.wikimedia.org/wiki/File:Number_of_uses_of_charts_by_year_of_latest_chart_data_in_English_Wikipedia_articles.svg).

That category is the data source. My earlier post was removed so apparently linking to the data source and the page with the info on how the chart was made is not enough so I’ll provide more details here: it was made using the https://glamtools.toolforge.org/glamorous.php tool and visualized using matplotlib. If you want more details like the full matplotlib code you can go to the file page – please don’t remove it again and just comment if I need to put more info directly into this comment.

This is part of an effort to identify and update old/outdated charts in English Wikipedia, [WikiProject Data Visualization](https://en.wikipedia.org/wiki/Wikipedia:WikiProject_Data_Visualization) (I updated quite a few data graphics before making this chart; edit: and there are very few editors who update charts, basically one can count them on one hand and it’s only possible systematically / at scale since I made the category two years ago).
