Cascade of Pies Intrigues

iStrategy arranges pie charts to explore relationships and display relative importance

This alternative to a simple rectilinear arrangement of charts is not only more visually appealing, but also encourages the viewer to consider how the different datasets relate to each other. At the top of the infographic a bright red pie shows the total media market. As the viewer travels downward, different aspects of the mobile market are presented. Related topics are grouped and identically colored. Additional breakdowns of pie slices are shown as overlapping pies.

The Power of Showing Not Telling

The new book “An Illustrated Guide to Income in the United States” presents a comprehensive collection of infographics, maps and charts looking at the history of incomes and occupations in the United States.

Data can be a powerful persuader. Instead of pages and pages of text spoon feeding the reader with conclusions, this book presents a large dataset in a format that empowers the reader to study the data itself to draw their own independent conclusions.

Squandering Ink and Taxing Our Patience

Newsosaur decries too many words

“Many stories can be told better in charts, pictures or infographics than in the hundreds, and sometimes thousands, of words that tend to be the go-to medium for most newspaper journalists. When the story is about a new public opinion poll about gun control, I jump straight to the tables  that tell me who’s for it and who’s not. When trying to wade through a complex investigation of corruption among the political elite in China, I find it easier to follow the money in the infographic than reading columns of gray prose.”

Spiral Charts

Scientific American plots hugely dissimilar values.

When some values in a bar graph are very large and others are much smaller it is difficult to discern the differences. All of the small values produce bars that are barely visible so there is no way to see the differences among the small bars. The spiral chart solves this by bending the bars. The high values spiral around and around. Differences in the low value bars are still clearly visible.


Killer Graphic

Scientific American graphic succinctly drives home the point

It may be a cliche that a picture is worth 1000 words, but this graphic certainly proves the point. Three bar graphs showing how life expectancy is altered by our “good” and “bad” habits.


Quarters Don’t Compare

Calendar quarters are not really comparable

Fortune’s CNN Money takes a closer look at Mac sales and discovers that what appears to be a decline is actually the opposite  Wall Street forecasters are projecting a quarter-on-quarter decline in Mac sales for Q1 2013. This looks bad for Apple, but a closer look reveals that it really isn’t so.


Taking these numbers at face value does not take into account that Q1 last year had 14 weeks, not the usual 13. Adjusting for the number of weeks in the quarter produces a increase in sales from 5 to 10 percent — a big difference in conclusion.

So when comparing quarters, be sure that you are comparing apples to apples.
