More than 50% of the world’s population uses the internet today. The rapid growth of technologies and the need to establish an online presence have resulted in an unimaginable amount of information floating around the world wide web. As companies try to leverage data and increase profits, there is an unavoidable competition to convert all this information into useful data.
Why is there a need to visualize data? Why not use a simple, traditional excel spreadsheet to show the data in specified rows and columns? Well, according to research done in the field of psychology, people tend to gain 90% of the knowledge through their sense of sight. With this in mind, transforming those rows and columns into charts and graphs helps people digest the data accurately and understand data more deeply.
In some cases, particular variations and patterns that were not clear previously become clear and evident. It becomes vital when companies need to make business decisions. Simple pie-charts and line graphs can uncover details and patterns that might save the company hundreds of thousands of dollars.
Unsurprisingly, Tableau has found itself in the Leader’s quadrant in the Gartner’s Magic Quadrant for Analytics and Business Intelligence Platforms. It’s a chart by Gartner which aims to evaluate the performance of 21 providers who they have deemed most significant. It consists of four quadrants, Leaders, Challengers, Niche Players, and Visionaries. Companies are given spots depending on the levels of completeness of vision and the ability to execute.
Tableau has had a place in the Leaders quadrant for eight consecutive years now, and it’s only closest competitor is Microsoft. Microsoft offers an entire suite of services while Tableau sticks to one. The situation draws comparison to the saying, “Jack of all trades, master of none”. Microsoft seems to be the jack in this case, while Tableau focuses on doing one job to its best.
Tableau has become the go-to Business Intelligence (BI) tool for most companies around the world. The majority of the Fortune 500 companies use Tableau for their data visualization. In the Business Intelligence niche alone, Tableau has a 16% market share. The software company raked in about $1.7 billion as of 2020 and forecasters expect this to cross $2 million in 2021.
With that said, here are 20 reasons you should learn Tableau.

Whether you are a “fresher” who is right out of college or a seasoned software engineer, acquiring Tableau as a skill will raise your job prospects.

6) Tableau Has Better Data Integration
With the help of data blending, a feature released in Tableau 6.0, users were able to now mix data from different sources to create eye-catching and insightful charts and graphs. This seamless data integration is one of the most talked-about features of Tableau. The data blending taking place here is possible with the help of one primary and many secondary data sources. Check out this whitepaper that talks more in detail about this.

Tableau offers many nuggets of features within the tool that make data alteration and manipulation.

Although Tableau serves mainly as a visualization tool, a service like Tableau Prep provides functionality for it to perform as an Extract-Transform-Load (ETL) tool.
8) Tableau Can Easily Visualize Large Amount of Data
If you consider everything, Tableau seems to be the holy grail when it comes to data visualization. The effortless ease with which users can produce appealing dashboard speak volumes about how well thought out Tableau is as a tool.

Tableau works on a framework that can withstand the analysis of high amounts of data. Given the transfer of data within each company at any given time, this becomes the need of the hour. With the ability to pause auto-updates, handling large datasets becomes a piece of cake.
10) Tableau Organizes Your Data Well
Tableau offers users the ability to organize the entire data visualization and analysis process in a compartmentalized fashion.

Right from the interactive wizard to its well thought out layout, everything about the Tableau interface screams interactive. The learning curve for Tableau is much less steep compared to a lot of other tools available in the market.
12) Maps & Geo Now Supported in Tableau
Another feature of Tableau that is underrated is the ability to analyze geospatial data. With the help of geocodes, Tableau users can now plot and analyze data on a map. It breathes new life into your data and helps visualize data that would have otherwise been very complicated to represent. With 16 levels of zoom and a wide variety of maps to choose from, the possibilities are endless.
13) Tableau Can Connect To New Data Sources
With the help of Tableau Server, users can now share workbooks easily without having to worry about other issues. Tableau provides the functionality of connecting to a wide range of data sources. Gone are the days where you could only work with .csv files. Tableau supports connecting to multiple different file types. Tableau Public offers a limited set of file types, which is more than enough for beginners. Since 2019, the Tableau Catalog has been made available on Tableau Server and Tableau Online, which allows users to connect to both published data sources as well as databases from Tableau Server.
14) You Can Perform A Cluster Analysis in Tableau
Cluster analysis has always been a vital part of data analytics and this has never been easier since it was made available in Tableau. With the help of clustering, it has become easier to understand how similar groups are depending on the parameters we choose. Clustering has become a pivotal part of analytics and visualization in Tableau.
15) Tableau Has Data Filtering
The ability of Tableau to filter data has various benefits. Right from cleaning the data and removing unnecessary dimensions, to analyzing data based on certain conditions, this tool provides a ton of flexibility when it comes to what data undergoes analysis. Tableau offers not just to developers creating the visualizations, but also for the end-users. Data filtering has a positive effect on the overall efficiency of the data analysis process.
16) Merge Separate Data Points with Tableau
Tableau also allows for flexible plotting with the help of merging separate data points. By using the dual-axis functionality and the ability to have multi-dimensions, users get the provision to plot multiple fields on the same graph. It, in turn, translates to having different and separate data points in one go.
17) Tableau is Affordable
Tableau offers different packages to suit a wide array of purposes. From personal to commercial use, they have it all. Considering the features you get and the depth at which data analysis and visualization are possible, the price is more of an investment. For individuals, a monthly subscription costs about $70, while for teams and organizations, Tableau offers more customizable options to fit their particular use-case.
18) Tableau is Easy to Learn
