After a lot googling and putting data into the right format, I was able to craft my first Tableau dashboard.

My first Visualization with Tableau
It has been a good week for me. I have pushed myself to learn Tableau within the shortest time and get things working.
I was asked to a site level data analysis for specific HIV care and treatment Indicators. The data was from an Access database application. I first had to split the database to get to the back end of the database. The second and major headache was to get the data in the right format that Tableau will accept. I used Excel to transpose the data to a format that Tableau accepts.
I loaded the data and started getting my hands dirty with tableau. Eventually, I was able to come up with this

A not so gentle introduction to Tableau
It is my second week at my new work place. I am liking the place.It has been a hectic two weeks. The Introductions, orientations and all.
And now comes the time to settle down...and then the data, and of course the request that comes with it. OK, that is not a big deal, let me see the data. And what do you use here for data analysis?
"Tableau"
Whaaaaaat? What is Tableau? I ask. A tablet? a book?
"Tableau is a data analysis software", I am informed. "And that is what we use here for data analysis. That is what you will be using".
I slump on my desk, just like my son usually does when he is told to do something he does not like. He picked it from Sponge bob square pants. Well, that said, there are no pants here,I realize that I don't have all the time to whine, I'd better get myself started with this Tableau monster. So first, I head to Mr. google and google what this Tableau.
I find out that Tableau is a BI software more so like others BI tools I have used elsewhere: Actuate, SAP Crystal Reports, SQL Server BI stack, Pentaho, Jasper Reports and of course the master - Excel. I come to also realize that it is highly regarded and is among the top BI tools as per this Gartner report. It is placed on top, ahead of many "Big" players in the data analytics field. They are placed above Qlik View, SAP, IBM, Micro strategy and even Microsoft itself. (not that I feel they are the best, but I have been using Microsoft BI software for some time now. You can download the report here
Ok, so i started to have some respect to this Software and the company. I spend my better part of the afternoon hearing more about it and eventually downloaded the free version - Tableau Public before I could get my licensed version. The license can cause an arm and a leg, especially for Africa and Middle east countries.
