The bar chart is vertically squashed due to too many bars.

May consider implementing: http://stackoverflow.com/questions/17617432/nvd3-force-specific-width-of-bar-in-bar-chart/17711885#17711885 to manually set vertical spacing.

However, even if individual bars are not well visible, they can be moused over. And the aggregate effect of the bars is compelling, even if the individual bars are not easy to see.
