Although I promised I will show you how to visualize the data using screen cast – I won’t do it. I started taping the screen and it took me more than one hour to actually explain basics, without going into advanced techniques, like name references, dynamic graphs and dash boarding (which involves a lot of use of functions like…

I have received quite a few emails on my last blog post. Most of the authors asked me how to create the dashboard that conveys clear and simple message to the viewers. Honestly, I am new in this area myself but I can point you to the following two papers by Stephen Few I found a must read: Graph design...
