What is Data Visualization?

Data visualization is the graphical representation of raw data using visual elements like charts, graphs, and maps. A visual depiction of this data can help analysts better understand and respond to data trends and patterns. It tells a detailed story that can be easily understood by an audience.

In the big-data ecosystem, massive amounts of information can be analyzed to make data-driven decisions that prevent losses and enhance a company's return on investment (ROI).

Why is Data Visualization Important? 

The purpose of data visualization is to organize available raw data from multiple sources and formats in a manner that is easy to understand. Data is then curated and represented in a more straightforward form. Any noise or irrelevant information is removed, while useful information is highlighted. 

Data visualization powers decision making by answering these key questions:

  • What are the relationships and trends?
  • Are there any outliers?
  • Does visualization enable a comparison of multiple values over different periods?
  • What trends do the datasets display?

As companies handle more data in real time, visualization becomes a key tool to make sense of the trillions of rows of data generated. While a delay can cost a company significant resources in manpower and money, practical data visualization tools can remove such losses while also increasing efficiencies. 

Where is Data Visualization Used?

Weather maps, real-time air-quality indices, annual income, and expense report spreadsheets, and Facebook page statistics are examples of data visualization. It is used in many other ways to help stakeholders make quick decisions.

Some common use cases include:

Data visualization for Health Intelligence

Tableau: The Ultimate Data Visualization Tool 

There are many data visualization tools to choose from, whether you are a data scientist presenting findings to an audience or business intelligence (BI) user looking for a practical way to visualize large datasets. Tableau is one such tool. Created in 2003, the interactive data visualization software lets you create charts, graphs, maps, and graphics without using code. It can be installed as a desktop app for visual analytics or as a server solution for online and mobile reports. Tableau connects to almost any database to create compelling visualizations that can be shared with a simple click. It makes data analysis fast with its dashboards and worksheets, which has made it a popular choice in all industry sectors.

Why Learn Tableau? 

The rich, intuitive BI Tableau dashboard gives senior executives and data scientists a simple way to tap into large datasets for visualization and reports within minutes. Because of this, Tableau has emerged as the preferred BI software for presentations, reports, and actionable insights. It also allows nontechnical users to publish interactive data visualizations on any topic, as well as create customized dashboards.

Tableau10 runs 100 times faster than existing solutions and can be integrated with the R programming language for a seamless visual analytics interface, making the exploration of complex data much simpler.
