Galileo, the world’s first information designer (Art and data analysis, Part II)

In the days of modern, high-resolution photography, it’s sometimes hard to believe that Galileo’s tools were limited to pen and paper. His observations of the moon are sketched with the precision of a scientist and the artistic prowess of a Michelangelo. His drawings are the data material for his analysis. It’s the artistic prowess of the reproduction – and not the mere ornamentation – that distinguishes first-class information graphics.

Using data as graphic elements: stem and leaf displays

John W. Tukey’s semi-graphic visualizations transform the actual data into graphic elements. Like most brilliant ideas, however, this one isn’t widely used.

Statistical thinking vs. statistical rituals, Part I

Means are often used as the sole representation to characterize distributions for a collective of data. Yet, these types of shortsighted visualization are highly dangerous. How can we present data so that it reveals more than it conceals – and still makes sense to managers?

Comparisons, Part II – Avoiding visual pathos

We often encounter cartographic visualizations as a way to explain spatial comparisons. Although they are great eye-catchers, there are rather difficult to use (well). Learn when (and if!) it makes sense to use these chart types to visualize business data.

The scale is your message

Chopping the axes of a graph is one of the most common forms of data manipulation. Stretching or squishing the scale is equally taboo. However, different scales might have their validity in certain situations.

In this German interview he explains that bad report design plagues companies of all sizes and industries.

The eight commandments of good visualization

Thou shall honor these eight simple visualization principles of Edward Tufte – or have a darn good reason not to! They apply for the first map carved in stone over 6000 years ago just as they do for contemporary Web sites.

Why 2.0? Welcome to Business Intelligence 7.0!

As most people in relationships know all too well (“You’re just like your mother!“), your selection of opening words will make or break any discussion. This holds true in the IT industry as well. Only there, you need to talk about something new or at least make it sound like it is. The proper terminology is equally important. But at all cost, avoid German translation. Not everybody fails as poorly as I did: Google cites 1,310,000 German pages for Data Mining and 846 for Datenmustererkennung (data pattern recognition), a term I tried to coin as repeatedly as unsuccessfully.
