Easiest way to serve out an HTML5 canvas?

this is a beginner question for web folks. I've never served out a web page, but I've prepared a data presentation using an HTML5 canvas (I wanted it to be interactive and viewable anywhere; the canvas works great), within an HTML file. It's in an HTML file that I can double click on, and it opens in a browser and does what I want it to do.

What's the easiest/best way for me to put this on the web so that I can send out a URL to anybody and they can view it? Please keep it simple, because while I'm competent at software development I haven't the foggiest about web stuff. :) Thanks!
