Easy, it is all in your browser.  It is all html and
javascript, and it is not compiled or minified.

Just save the page to you local drive.

Perhaps others can use it?  I try to keep the code simple
and tidy to encourage that.   It is necessary to provide
spectrum data on your web server in the right format.  I'll
document the simple format and how to generate the data.
