Archive of our Own - Haikyuu Fanwork Data Visualisation

The "Archive of Our Own" (AO3), a nonprofit open source repository for fanworks, has become one of the most popular archives for transformative works since its founding in 2008.

Haikyuu!! (ハイキュー!!) is a Japanese manga series written and illustrated by Haruichi Furudate. On this page I have collected several statistics about the fanfictions of the Haikyuu!! series. This was achieved by going through the tag "Haikyuu!!" on AO3. This means that any work not tagged with this was not considered. Works that are only viewable when logged in are also not considered as they cannot be saved with my script.

To explore the visualizations just start scrolling down! :)
This table shows how many works were finished per day. Only complete works are counted this way :)

You have reached the end! Thank you very much for looking through this. I really enjoy making visualizations so there might come a few more in the future. I have a full database with statistics about Haikyuu works. And there are a lot of interesting things I could make graphics with.

If you have anything specific you are curious about why don't you head over to twitter and ask me? :)

Some more technical details:

Used JavaScript libraries: skrollr and D3
I used python and postgresql for scraping AO3 and the creation of the database.
This project of mine is already a few years old but I recently remade some parts of it.
Visit the github project page for the code :)
