Hi Guys
With the advent of Tableau 8.1, a new graph feature was introduced which is the boxplot. In all honesty, even I do not know how to effectively use that chart type yet. I'm so glad of this good blog by Tom Hopper explaining the intricate details of the boxplot. Have a look at the entry below:

How to lie in DV?
Hi all,
We all have done it or heard about it, padding up our resumes to make it look better or using bombastic words in our reports to make it more elegant. And this is also not alien to the world of DV. See the ways how a DV is manipulated to NOT tell the story accurately, and how the manipulations would brig the wrong idea, and some, even the opposite to the public.

DV throughout History
In recent years, Data Visualization (DV) has been the talk of the town. At first, people were just looking for a better way to understand and interact with their data, and DV came as a very niche area in the BI universe. Now, DV is at its greatest time, businesses have adopted it for some time, but its the layman, the normal people like you and me who are now more exposed and embracing this new frontier. With the help of free tools like Tableau Public, DV is exploding now with new creative ways to understand and explain data.
Although it seemed like a recent phenomenon, using DV as a means of conveying an idea is definitely not new, don't be surprised that people who defined history like Florence Nightingale used DV in helping to save the lives of millions of soldiers at the turn of the 20th century. And we could have never known the importance of sanitation if it wasn't for her.
Take a look at this blog entry to see which DVs were influential in mankind's history.
Also, after watching the presentation, take a look at this site that lists historical DVs that represented critical milestones shaping our history:
