I went with the approach of hardcoding few sets generated by http://tools.medialab.sciences-po.fr/iwanthue/ http://tools.medialab.sciences-po.fr/iwanthue/ (which i think already been covered on HN) in my app. Just one set when i need <= 5 colors, one for <= 20, 50 and 100. Oh, and alternative set with different palette of colors when I need two diagrams on the same page. As a colorblind person I must say I was very happy with the results.
