A mapping application that allows a user to quickly see trends and current realtive expenses in countries around the world.
There are plenty of databases and static maps showing relative costs across countries, but it's hard to get a big-picture view without visiting multiple sites. Also, most reports and maps focus on USD and EUR as the base currencies. It's difficult for people earning more obscure currencies to find data from their perspective.
The application will provide a quick input form to generate a dynamic map based on the user's desired perspective. Data sets include exchange rate trends across specififed time spans, and relative costs that consider a currency's purchasing power in the domestic market.
While a wide variety of people might be interested in this data (business people, students, etc.) the primary targeted audience will be long-term travelers or potential expats. These people will be interested in the trends of their home currency abroad, and the the relative expenses of other countries.
- Open Exchange Rates currency API for historical and current exchange rates, a JQuery vector map that provides a local API, financial datasets, and possibly a travel-booking API
