A Flask server app which tracks visitor IP location and updates unique visitor count that can be integrated in a website. See the deplyoment here at https://dutta-alankar.github.io/website-visitor-stat-app/.
I have also provided a sample html client that can be modified and used in any webpage. The client also puts the geo-coordinates of the unique visitors on the map in a dynamic webpage.
Make sure to change the serverAddress in the html javascript of the client to point to your server.
statserver.py is the Flask server code that I'm using. I have hosted my server in https://www.pythonanywhere.com/.
You can choose whatever suits you.
To run the server, install all the dependencies using pip install -r requirements.txt
