We understand data better through pictures than by looking at numbers arranged in rows and columns. Representation of data in pictures is called visualization. Visualization answers important questions — ‘Who are my customers and what are their characteristics?’ ‘In which areas our sales are growing?’ ‘Why my sales are growing?’ Thus a combination of visual analysis and the power of data science elevates the data to a competitive advantage.

There are visualisation tools to organise and present information. One such tool is Tableau. It simplifies, energises and enlivens data science.

You have to start with visual analytics. Here Tableau filters are used. There could be data story telling. You can use the power of R and Visual Analytics.

Tableau software enables you to drag and drop your data into beautiful visualizations. It is end-to-end, flexible interactive visual analytics software. It can be used to create interactive graphs, charts and maps. The other tools are QlikView, Datawrapper, Plotly, Sisense, Excel and Zohoanatytics.

Tableau is easy to learn and fast to deploy. It is superior to Excel when it comes to visuals and dash boards. It makes raw data easier to understand. It takes 2-6 months to master Tableau. It is a free public platform.Tableau does not require coding. If you know SQL, it could be valuable to use Tableau. Tableau allows far more interactivity and is easier to make plots with than Python coding. Python is best when working with a variety of data that requires advanced analytics. Tableau SDK can be implemented using C, C++, Jawa and Python. Tableau SDK supports Python 2, and not Python 3.

Tableau appeared first in 2005. It was founded in 2003 in Moutain View, California and is currently headquartered in Seattle, Washington. In 2019, the company was acquired by Salesforce for $15.7 billion. It is a spreadsheet application used to organise and format the data. It is worth learning.
