jVectorMap for the Rails asset pipeline

Add it to your Gemfile:

gem 'jvectormap-rails', '~> 1.0.0'

You can add jvectormap-rails to your application.js file using a require statement like this:

//= require jvectormap

To add support for whatever maps you want to use, include them from the jvectormap/maps path:

//= require jvectormap
//= require jvectormap/maps/us_merc_en

The basic pattern is {country}-{region}_{city}_{projection}_{language}. For example, the map us-il-chicago_mill_en has a country of us (United States), region of il (Illinois), city of chicago, projection of mill (Miller), and a language of en (English). Other common projections include Mercator (merc), and Albers equal area (aea).

jvectormap-rails supports precompiling individual maps. Add an initializer to your app, eg. config/initializers/jvectormap.rb:

JVectorMap::Rails.precompile_maps << "us_merc_en"

Get a list of all available maps by running this from within your Rails app's root:

bundle exec jvectormap:maps
