This is a version of a chat server from swi prolog. It has been extended to have a map with pins that show where each person who is chatting is.

The chat users can collaboratively and in real time add shapes as annotations to the map. Users can choose a color and then draw a shape which is shared in real time with other users.

The next step of the project is to intregate some rules on shapes.

load my_server.pl and run

?- server.

This will start the server at port 3050.

Then you can see the page at localhost:3050, the website has been tested in chrome. You need to allow the site to share locations, the locations update every 5 seconds so you dont want to be clicking allow every 5 seconds!
