Sometimes it is not easy to get useful information from a stacked bar chart, see for instance
this blogpost at Support Analytics.

So-called inkblot charts, as discussed at Kaiser Fung’s
Junk Charts, allow the reader to focus on the evolution
of a time series.

Now how to make this kind of charts with R? I asked on
StackOverflow. The given answers led to an implementation
of an inkblot function. It is delivered with the wzd package on r-forge. Here is an example which visualizes the income per capita from
various countries, as reported by gapminder:

> #install.packages("wzd")
> library(wzd)
> data(gmIncomePerCapita)
> selection  inkblot(selection, min.height=1300)
