The following charts provide an example of dc.js used against 27 years of Nasdaq 100 index data. Although it is just an example, using it you can already ask some interesting questions. If I am going to gamble whether Nasdaq 100 will gain or lose tomorrow what is my chance? Is Friday or Monday the most unlucky day for investors? Is spring better than winter to invest? Can you find the outliers? When did the outliers occur?
