 ##Summary
 
-Density maps are great ways to show complex underlying data in a simple and visually appealing way. We have developed a couple of custom tools in CartoDB to make it really easy, here I'll show you how to use them. In this tutorial, we are going to use data from 2012 bicycle crash reports in Chicago. This is a really interesting dataset that can be used for a lot of reasons. The data was originally collected by the Illinois Department of Transportation and the most up-to-date datasets can be found over at http://chicagocrashes.org.

 For this tutorial you are going to need a code editor that will allow you to edit HTML files. You will probably run into problems if you try to do the tutorial in a document editor such as Word or Open Office, they often add invisible markup that will make your file unreadable by web browsers. We recommend taking a look through the list here, http://en.wikipedia.org/wiki/Source_code_editor. In particular, TextMate or Notepad++ will do the trick.
