When some of the datasets are presented in space, the data points overlap one another to the extent that the visualization is largely ineffective. See AllMarkets/World/The Russian Exchange.
Likewise, in other datasets the object and axes labels are very large, and or they are not easy to read. For example, for the dates on the grids you have something like 2005/09/12 displayed, the display of which is sometimes bigger than grid itself . For example see Banking/MorganStanleyinthenews/.
