One of the most frustrating issues I face in my professional life is the plentitude of ineffective reports generated within my company. Wherever I look around me is plenty of junk charts, like barplot showing useless 3D effects or ambiguous and crowded pie charts. I do understand the root causes of this desperate state of the art: people have always less time to dedicate to reports crafting, and even less to dedicate to their plot. In the crazy and speedy-going working life, my colleagues have no time and for learning data visualization principles. Even so, this remains quite a big problem since a lot of time and money-wasting consequences come from poorly crafted reports and plots:

It was around midnight here in Italy:
I shared the code on Github, published a post on G+, Linkedin and Twitter and then went to bed.
In the next hours things got growing by themselves, with pleasant results like the following:

The R community found ramazon a really helpful package.
And I actually think it is: Amazon AWS is nowadays one of the most common tools for online web applications and websites hosting.

Introducing Afraus: an Unsupervised Fraud Detection Algorithm
2015/07/02
The last Report to the Nation published by ACFE, stated that on average, fraud accounts for nearly the 5% of companies revenues.
on average, fraud accounts for nearly the 5% of companies revenues
Projecting this number for the whole world GDP, it results that the “fraud-country” produces something like a GDP 3 times greater than the Canadian GDP.

In the early ‘900 Frank Benford observed that ’1’ was more frequent as first digit in his own logarithms manual.

2014/11/19
If you have a blog you may want to discover how your website is performing for given keywords on Google Search Engine. As we all know, this topic is not a trivial one.

Feeling this way?
