How big is it?

 Check out this online magnifying glass (use the slider!).
 
Some cells are visible to the unaided eye
The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny.

Things that make you go "Hmmm": drug deaths

[From Information is Beautiful]

Visualising the Guardian Datablog:

I’m doing a regular weekly visualisation for the excellent Guardian Datablog, the front-end for an amazing library of statistics and data, lovingly hand-gathered by The Guardian.

My first post is about Deadly Drugs.

 IiB presents this chart:



Check out the article on The Guardian blog for detail and data. You want both right?

I'll second that.

A Periodic Table of Visualization Methods




Each element represents a different type of data visualization, and hovering the mouse-pointer over any of them will pop-up an example. "Hi" stands for Histogram as demonstrated in the captured pop-up below.



Very nicely done! See for yourself.

This happy accident occurred while I was searching for "element-pun" material in response to comments on a recent post at The Endeavor. Thanks John!

"Hey, get your hand out of my pocket!"

After seeing someone post on FaceBook this obviously misleading graph ...
[edit: link removed, picture inserted, incomplete sentence left as-is]
...presenting a comparison of McCain and Obama tax plans. I didn't think too much of it at the time. I did, however, post this note on my wall in response to an anti-Obama sermon someone else had posted (No kidding, the present "The Parable of the Talents" as an argument that Obama's tax plan is not biblical!):

Dan Eastwood is fairly certain the world will not come to an end when Obama gets elected, but snickers a bit at the people who whine about it so.

To which a good friend of mine replied:

"I, too, am pretty sure the world won't end... Of course there's a bit of distance between "world ending" and "hey, get your hand out of my pocket!"

I was about to write back something about "hands in pockets" and that hands of taxation are already in everyone's pockets, so I searched "tax plans" for ammunition, and how this article from Freakonomics: Competing Tax Plans: Two Perspectives.

Voila! The same misleading graph appears again, along with two other ways of presenting the same data that look very different, and a nice discusion. A little real information is better than a pointless argument any day. Rather than repost all that here, I urge you to go read the the Freakonimics article, it's short and well worth the effort. Or, if you are ambitious, go read this newly released report by the Tax Policy Center.

And who IS John Galt, anyway? (Thanks Matt!)
