API for access US data sets

#Installation

DataUSA is a web platform built using Flask, an open source Python library for interacting with HTTP. this installation guide is written assuming a Linux or Linux-like environment. The following software is required to be installed locally in order to get DataViva running:

• Python
• Postgres
• Redis (at least version 2.8.6)

1. Clone from Github git clone https://github.com/Datawheel/datausa-api.git

2. [optional] Create a virtual environment. We suggest installing virtualenv with virtualenvwrapper especially if the machine you are using is used for many other web projects. This allows python libraries to be installed easily and specifically on a per proeject basis.

   Once this is complete, run the following to initialize your datausa environment.

   mkvirtualenv datausa
