Welcome to the world of Data Visualizations
Data Visualization is an art of presenting the data in a manner that even a non-analyst can understand it. A perfect blend of aesthetic elements like colors, dimensions, labels can create visual masterpieces, hence revealing surprising business insights which in turn helps businesses to make informed decisions.
Data Visualization is an inevitable aspect of business analytics. As more and more sources of data are getting discovered, business managers at all levels embrace data visualization softwares, that allow them to analyze trends visually and take quick decisions. Currently, the most popular tools for visualizations / data discovery are Qlikview and Tableau.
This is the first part of the Tableau series. The series is as follows:

We see that every second individual in today’s time calls themselves as a Data Scientist or a Data Analyst, but sadly most of them don’t know about this wonderful software that is there at hand. TABLEAU, is an amazing software, can be used to create niche infographics with a mere drag and drop simulation. One doesn’t need to be a pioneer of Machine Learning Algorithms, or an ace Statistician to be able to fiddle around with this Software.
