I didn't know GoG existed when it came to writing up a couple of tutorials[1][2] on how to go about building a (very, very simple) charting tool[3] on top of my canvas library. I'm going to have to re-assess those lessons, and add some links to other guides, now that I know about them.

Luckily for me, the main purpose of the lessons was not so much about how to build a charting tool, but rather concentrated on how to break the code into modules in the hope that some of the modules could be reused in other, similar projects.

If I'm making obvious mistakes in the approach, or code, that I set out in the lessons then feedback is always welcome so corrections/improvements can be made to them!
