This is my first-ever blog entry and I would like to start sharing my experience
with Data Visualization and Analytics and some work that I’m doing around it as part of my
daily work
First I’m getting the chance to test some products available
on the market like Microsoft Business Intelligence, SAS Visual Analytics and
Tableau among others.
I started reading an interesting book related to Data visualization called “Information Dashboard Design” written by Stephen Few, what
basically are giving some tips and sharing some common bad practices done creating
Information Dashboards.
I’ll share one basic example that it’s included in this book
and represent graphically how Visual Analytics/reporting helps to take fast a
better decisions by pulling the right information or highlight the relevant
one. Let’s start with this simple game. How many 5s are included in the list
below:
