Hi!
I require MongoDB for my tool, which allows the user to visualise the cumulative anonymous edits made to any Wikipedia page on a world map. I'm using CartoDB's APIs for visualising the edits on a world map.
MongoDB is used to georeference the IP addresses from MaxMind's free Geolite database. I'll be running a node.js server with standard modules (express, request, mongodb.) After that the data is pushed to CartoDB's servers and the visualizations are generated using their APIs.
I worked as a Data Viz intern with the Comms team during the summer. This tool is a continuation of the same project.
Some example of the maps which the WMF-Comms team will be generating: http://cdb.io/1INigj5 (password: wikiCartoDB) or https://twitter.com/ReaderMeter/status/617341650415812608 etc.
My tools-lab username is: Dhvanil
The tool name is: geoplotter
I have the entire code running on my local machine.
Thanks!
