plotting data

I made a plot of a curve, and it looked pretty smooth:

But when I looked at the data, it seemed like the gaps between points might be bigger than I thought. To better see the gaps, my first thought was to plot points, rather than draw lines between points, but it wasn't clear to me how to do this with an html canvas. So I drew lines of different colors between points, which was easier:

And I thought it worked well. This is all.
