Importance of the data visualizations:

Tableau data visualization is an essential aspect of the data analytics process. It aids data scientists by presenting raw data in an intelligible manner. Also, non-technical users can benefit from the visualization to make better decisions. A data scientist should grasp data visualization abilities to better interact with end customers.

Data visualization allows data scientists to effectively communicate the results of the data analysis to end customers, allowing them to spot hidden patterns in data. It also assists outcome in better understanding the company's exact status and productivity to make much better judgments.

Companies can uncover the reasons affecting their growth and areas wherever they want to develop by visualizing the raw data. It also assists them in determining the relationship between the independent variables and calculating the risks associated with changing them.

Data visualization tools:

Here are the best 5 data visualization tools in the market. They are:

● Tableau

● Qlikview

● Domo

● Microsoft Power BI

● Excel


Tableau is a popular business intelligence application that is used by a variety of companies for data processing, visualization, report preparation, and publication. This provides a straightforward and user-friendly interface that allows users to connect, clean, and transform raw data into actionable insights.

Tableau could connect to datasets on-premise and in the cloud environment, including Excel spreadsheets, CSV files, Open Database Connectivity (ODBC), Oracle, Azure, or Google BigQuery. Several businesses utilize Tableau for sales data analysis, consumer segmentation, budget tracking, consumer behavioural analysis, data categorization, and predictive modelling.


Qlikview is a visual data analytical environment that runs in real-time. Qlikview cannot perform the same level of visualization as other BI solutions. With the help of its dynamic models, you can analyze your data in multiple dimensions.

Qlikview offers a variety of ad hoc queries that enable fast decision and data access. It may also integrate a variety of data sources & visualize the essential data to create unified reports and dashboards. However, there are several distinctions between Tableau and QlikView. Tableau, for example, allows for quick drag and drop, making graphical inputs simple, whereas QlikView requires writing logic for regions where graphic changes are needed.


Domo is a cloud-based data analysis platform that enables companies to do data analytics and make data-driven decisions to improve their performance. Domo's business cloud is an open-source platform that allows users to connect to various unstructured and structured data sources.

Domo has actual data visualization capabilities that may use to generate live dashboards and reports. Thanks to the superb UI features, the user can construct an interactive display with sparklines, dashboards, and useful widgets.

Microsoft Power BI: 

Power BI seems to be another robust technology numerous businesses employ to deploy business intelligence capabilities. This is a collection of algorithms that enable users to execute data analytics and visualization to create visually interactive reports and dashboards.

Power BI uses AI capabilities like Power Query and Power Q&A to let users visualize data and produce highly customized reports. Non-technical individuals could use Power BI to uncover hidden connections and incorporate data. There are several distinctions between Power BI and Tableau, there are several distinctions, and Tableau allows any graph, bar, or chart, while Power BI only has regular charts, graphs, and maps.


Excel is a widely used spreadsheet programme that includes some of the best visualization tools. One can use excel to do complicated computations and data visualization by a competent professional.

Excel may be used to swiftly analyze stored information in sheets and illustrate it using graphs and charts for internal purposes. However, data connectivity and graphics generated corporate dashboards and reports are limited.

What is Tableau?

According to Gartner, Tableau has been one of the best business intelligence and analytics products available. Tableau's business story is truly inspirational. Companies use widely to make sense of data in a visually appealing style. Tableau can work with any data type, including organized, unorganized, and semi-structured information.
