This python script analyses interactions between users from a given Whatsapp chatlog and stores results in an infographic.

If you are on MacOS, you will need to install a different backend for matplotlib to render emojis. This blog post describes how to install mplcairo on your system.

How to export a Whatsapp chat history:

1. Go to a users profile
2. Scroll down and select 'Export Chat'
3. Select 'Without media'

This results in a zip file, which you can then extract, and paste the chats.txt into the chat_logs folder in the current directory. In the main.py file, simply change the string in load_file("chat.txt") to the name of your text file.

After running main.py, the results should be stored in output/poster_$user1_$user2.pdf
