On 18 Jan 2009 the table of data was removed (with no comment explaining why). But the text of the article still refers to the table, which reference is confusing to the reader. Although the table of data does take up some space, I think it is helpful in explaining the chart. After all, the whole purpose of a bar chart is to visualize data.
Tables are preferable to graphics for many small data sets. A table is nearly always better than a dumb pie chart; the only thing worse than a pie chart is several of them, for then the viewer is asked to compare quantities located in spatial disarray both within and between pies – Given their low data-density and failure to order numbers ...
A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart and has been identified as the prototype of charts. [1]
Data presentation architecture weds the science of numbers, data and statistics in discovering valuable information from data and making it usable, relevant and actionable with the arts of data visualization, communications, organizational psychology and change management in order to provide business intelligence solutions with the data scope ...
They can also provide insight into a data set to help with testing assumptions, model selection and regression model validation, estimator selection, relationship identification, factor effect determination, and outlier detection. In addition, the choice of appropriate statistical graphics can provide a convincing means of communicating the ...

GeoGebra is open-source graphing calculator and is freely available for non-commercial users.
The scientific argument is: In a perfect world, everyone would be as facile as scientists are at evaluating data, and scientists find bar charts easier to use. The pragmatics are: Only a small part of the population are scientists, and bar charts are less assessable to them.
