Why Data Visualization is important??

Data Visualisation is one of the processes in the data science process, according to which data is visualised after it has been collected, processed, and modelled to conclude. Data Visualisation is part of the data presentation architecture (DPA) discipline, which strives to efficiently identify, find, modify, prepare, and transmit data.

For similar reasons, sophisticated analytics relies heavily on visualisation. When a data scientist is creating advanced predictive analytics or machine learning (ML) algorithms, it's critical to display the outputs to keep track of outcomes and confirm that the models are working as expected. Because of this visual representations of complex algorithms are usually easier to understand than numerical outputs.

In the Big Data world, data visualisation tools and technologies are essential for analysing massive amounts of data and making data-driven decisions. Data Visualisation is the graphical representation of information and data. By utilising visual features such as charts, graphs, and maps, these tools make it simple to evaluate and comprehend trends, outliers, and patterns in data.

The Future of Data Visualisation

The field of data visualisation is entering a new epoch. Emerging intelligence sources, theoretical advancements, and multidimensional imaging innovations are altering the potential value of analytics and insights, with visualisation playing a vital part. The fundamentals of effective data visualisation aren't going to change. Next-generation technology and evolving cognitive frameworks, on the other hand, are expanding the boundaries of data visualisation, transforming it from an art form to a science.

In retrospect, the elements of effective data visualisation, such as substance, context, and actionability, have gotten a lot of attention. A brief overview seems in order as timeless tenets that will continue to be vital regardless of medium or format:

  • ·        The importance of data visualisation should not be underestimated. While imaginative images can help with engagement and recollection, they can't compensate for a lack of substance. "Every single pixel should testify directly to content," says purist Edward Tufte.
  • ·        The visualisation should be realistic and relevant to the situation. Billion Dollar O'Gram by David McCandless is an example of how embracing the wider picture may provide more meaning. "Absolute figures in a connected environment don't give you the complete picture," McCandless says. They aren't quite as accurate as they could be. We need relative figures that are linked to other data to provide a more complete picture."

Why data visualization, is important for any career?

It's impossible to think of a job that wouldn't benefit from a greater understanding of data. Every STEM job, as well as disciplines such as government, banking, marketing, history, consumer products, service industries, education, and sports, benefits from data understanding. Visualisation is one of the most valuable professional skills to learn because it is so common. The more successfully you can use that data, the more graphically you can present your arguments, whether in a dashboard or a slide deck.

Data science is becoming increasingly popular. Skillsets are changing to accommodate a data-driven environment. When data informs the who, what, when, where, and how, professionals' ability to use data to make decisions and use graphics to communicate stories about when data informs the who, what, when, where, and how is becoming increasingly valuable.

Different Types of Visualisation

When you think of data visualisation, simple bar graphs or pie charts are usually the first things that come to mind. While they are an important part of data visualisation and a common starting point for many data visualisations, the suitable visualisation must be matched with the appropriate data set. When it comes to data visualisation, simple graphs are just the tip of the iceberg. For successfully and engagingly presenting data, there is a range of visualisation options. Some of the most prevalent types of data visualisation are as follows:

  • Charts
  • Tables
  • Maps
  • Infographics
  • Dashboards
  • Histogram
  • Matrix
  • Scatter plot (2D or 3D)
  • Timeline
  • Wordcloud

Data Visualisation Tools

Data visualisation technologies make creating visual representations of massive data sets easier for data visualisation designers. When working with data sets including hundreds of thousands or millions of data points, automating the visualisation process makes a designer's job much easier, at least in part.

Dashboards, yearly reports, sales and marketing materials, investor presentation decks, and nearly anywhere else information has to be digested quickly can all benefit from these data visualisations. The following are some of the most common types of data visualisation:

  • Tableau
  • Power BI
  • Infogrames
  • Google charts
  • Matlab


It can be difficult to determine which visualisation to use because there are so many options. When it comes to data visualisation, users should consider things like ease of use and if a tool contains the features they require.

Remember, however, that data visualisation is only one half of the equation; you must also consider what else goes into developing a great data visualisation.
