The Visualization of Quantitative Data


Glancing at the numbers, can you predict the plot?

Perhaps, but a graphic yields quicker analysis.


My boss suggested that I read "The Visual Display of Quantitative Information" from the laboratory library. Skimming through the book, it was interesting enough that I would consider reading it in my leisure time. However, I was undertaking my 1 year sabbatical from reading, so I never got around to reading it.

Then recently, an accidental blackout happened at work and without network access, I had to find something to keep myself busy. Despite not making the most concerted effort, I managed to finish most of the book by the late afternoon when the power came back on. I finished the book some time afterwards.

I highly recommend that anyone required to any data analysis read this book. I'd still recommend it if you don't do any data analysis. Data tables have their place, but well crafted data graphics enables one to process large amounts of data quickly. Another example:


The cover picture is actually a timetable for the French train system. I'd say it's a tad more efficient than the number tables from those Translinks pamphlets.

Wrong time. Wrong place

Historically, man's ability to store excess calories as body fat has been vital for surviving famines. Today in non-impoverished countries, food is plentiful and excess consumption is the new problem.

These thoughts came to me after finishing some stuffed French toast at the local cafe. I considered ordering a second entree, but my expanding waistline prevented me from otherwise doing so.

Instead of being a coveted ability, my appetite is a burden.
