.. class:: infomark

**What it does**

This tool creates a graphic representing a DNA sequence.  
The graphic is derived from the sequence, but is not a literal representation. It is intended to be an aesthetic visual based on the sequence. Even a small change in the input sequence will result in a drastically different image. See [here](http://nstoler.com/misc/yourgenome.html) for a full description and rationale.
