What is data visualization, and why did it become so crucial in today's world of analytics? In the era of information overload, inferring patterns from large collections of data can prove to be challenging. Scraping off the mess comes down to data visualization, which is present in cool little words of representational information. You are a learner, a data fanatic, or a full-time worker; the art of data visualization can give you an edge. This article will tell you not only what data visualization is but also why it occupies such a prominent spot in any data analytics course in Pune or any other place.
What is Data Visualization
Data visualization, in the easiest terms, is a graphic representation of data and information.

In this way, it becomes simpler to detect trends, patterns, and outliers within large sets of data. Just think that you receive a spreadsheet containing thousands of entries; it is hard to determine the meaning of these numbers. However, when the same information is given in the form of a bar graph or a line graph, it is a lot easier to read about the distribution of the information and how it relates.
The Role of Data Analytics in Data Visualization
Data visualization is one of the modules that constitute a part of the curriculum of any course in data analytics . It is so since data analytics is not just about number crunching.

Methods of data visualization, such as histograms, pie charts, scatter plots, and heat maps, aid in converting complicated analysis into a simple, picturesque format.
These visuals not only contribute to the improved analysis of information by professionals but also aid the process of relaying the findings to non-traceable audiences as well. An effective picture is worth a thousand words, and it can convey the message more effectively and faster in comparison to a report.
