Approximating Areas Interactive

Another coding project to share today: an online interactive for demonstrating the areas under a curve for a Riemann sum.

I started work on this a couple of months ago, then forgot about it. I'm probably not teaching Calculus in the near future, so I lost some of my enthusiasm for completing all the ideas for this project. But given the work I'd already put into it, I thought it would be worth sharing what I've got anyway.

You can find it here:

I might come back to this at some point. Let me know if you've got any suggestions, or any functions you'd really like me to add to it.

I've also done this concept as an activity involving cutting and pasting.
