Congratulations for completing this project! Not sure what you mean by write-ups, but I am interested.
On a slightly unrelated note:
Wow!
This project is extremely interesting.
It reminds me of something I did between last year and this year where I calculated the result of the 2019 European election in Italy by parliamentary first-past-the-post constituency.
It was a freaking lot of work (some constituencies occupy close to 100 municipalities) and I could not have exact results for constituencies that split big cities, but I am very proud of it.
And now I am starting to make maps out of it.
Oh well, I did actually end up posting the maps based on that on this forum. Lol
