Add O(nlog^n) to Chart

[caspar]

Can we replace the existing image with the one below?
Shell sort has time complexity O((nlogn)^2) in its average and worst case, but this function is not included in the chart provided.

Here's an iframe linked to an interactive version:

Thanks for creating a google chart version, this looks a lot better than the one I had before. Right now I'm using a hand crafted SVG version with inline labels rather than a legend, and I intend for the colors to match up with the page colors (red yellow green).

I'll look into adding O(nlog^n). Originally I was just wanting to add the common complexities.

Closing this ticket for now.
