A simple rails application for visualizing data on a 3D planet earth.
Demo on Heroku
No extra setup needed. Simply download the source code, bundle install
, rake db:migrate
, you know the drill.
This application allows for batch importing as well as manually entering and adjusting data. Changes will be reflected on the canvas immediately.
To import, the file must be in csv format with four columns. The column names are (from left to right) "city", "state", "country", "count" (all lower cases).
! The demo app uses Google's free Geocoding API which allows for up to 2500 queries/day. Please limit your import file to a few rows. If you wish to do a massive data visualization, download the source code and modify geocoder's setting with your API key. Instructions Here.
