5 reasons why Tableau is the best data visualization tool
Data Visualization is an integral part of a data analyst job. Any inferences drawn from the data needs to be conveyed to others in a manner that is easy to understand. And what better way to understand a bunch of numbers than to put it in the form of a graph or a chart? Visuals have always been used as a medium to communicate complicated messages with ease. Its importance has grown manifold now that we are dealing with a tremendous amount of data.
If you work in a job that requires you to do data visualization, then you have definitely heard of Tableau.
It is one of the most powerful and commonly used visualization tools. Its popularity is growing by leaps and bounds. When it comes to Tableau, all the praises are well-deserved. Due to its widespread adoption this is the perfect time for you to get data visualization with Tableau training. It is truly one of the best visualization tools available right now. Here are a few reasons why you should opt for Tableau for your visualization needs.
One of the greatest things about Tableau is its ability to create interactive visualizations. Using this feature, you can actually display a huge amount of data in great detail. But the data is not all displayed at once. A higher level of data is shown and as the user interacts with the graph or the dashboard, more details are shown. This has two advantages. The first is that a single dashboard or a set of dashboards can provide information to people at different levels of the organization who may be interested in different levels of abstraction in the data. The second advantage is that this allows users to get the bigger picture and at the same time drill down to the details when needed. It completely eliminates the need for creating a different set of visuals for users who are at different levels in the organization. Instead, the same dashboard can be shared with multiple users and the users get to decide what level of aggregation of data they would like to see.
Easy to use
Any software or tool that is difficult to use will need you to learn a whole new set of skills that can take a long time. Many professionals want to learn new tools, especially ones that can help their career, but are faced with a time crunch to do so. Anyone can take the data visualization with Tableau course and become an expert in using Tableau within a short span of time. Most of the actions can be performed by simple drag and drops. Moreover, you don’t need to know any programming language to use Tableau effectively. Anyone, with a technical or non-technical background, can easily learn to use this software.
Ability to handle huge amount of data
As mentioned before, Tableau can handle vast amounts of data with ease and without any significant delay. You can even optimize the speed and improve its performance using various techniques. It allows users to make live connections to databases. Any changes made to the database will be instantly reflected in the visualization on Tableau. Another way Tableau can optimize the speed is by using Extracts. These are essentially snapshots of data that can be quickly used for creating a visual. Both these features are just examples of how much data Tableau can handle and how it has ways of speeding up the visualization process.
Sometimes you have data from multiple sources that need to be brought together into the same visual. In such situations, the data blending feature of Tableau can be very helpful. Data blending works even if the sources are at different levels of granularity. The main reason for this is that Tableau keeps the data separate and just displays the visual with all the information. This feature eliminates a lot of the groundwork that is usually needed by other tools when you are accessing data from different sources.
Real time data exploration
Many times, you just need to look at the data and see if there is a pattern or a trend. You may not really know what to expect. Tableau works very well in cases like these. It doesn’t expect you to have a specific goal in mind while creating the visual. You can just display all the information together and see if a pattern emerges. You are exploring the data in real time. You can even add or delete some of the information as you explore and see the results.
Improve your visuals using Tableau
As seen from above, Tableau has some unique advantages over its competitors when it comes to data visualization. No other tool can come close to what Tableau has to offer. By taking data visualization with Tableau training, you can add a valuable skill to your resume and enhance your capabilities.
