###This guide will give you the tools and show you how to download from the OpenStreetMap Overpass API on Windows. These steps were documented while setting up a Windows 7 64-bit machine.###

cURL and Wget are similar utilities to help you download things from the Command Prompt, either one will work - I think cURL might be easier to setup, but depending on your IT restrictions, etc. one or the other might work. You DO NOT need to do both steps A and B, one or the other. But if one method fails, try the other!

• A - cURL 0. get cURL
  1. download http://curl.haxx.se/latest.cgi?curl=win64-nossl from your closest mirror
  2. depending on your operating system version, download and install the appropriate Microsoft Visual C++ Redistributable dll from this webpage http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/the-program-cant-start-becuase-msvcr100dll-is/5c9d301a-2191-4edb-916e-5e4958558090 - - this is because you would get an error message `The Program can't start becuase MS

Part 1

Proof of concept

Say, you want to save your D3 application in a CouchDB database. This is just a proof of concept that this is possible. I use the »Focus + Context« diagram by Mike Bostock (http://bl.ocks.org/1667367) as an example.

Prerequisites:

• A running CouchDB (see http://couchdb.apache.org/; in my Windows installation CouchDb is started as a Windows service when Windows starts).
• An installation of couchapp (how to install couchapp, see http://couchapp.org/page/index).
• Your favorite editor.
