Why is data visualization important for data analytics?


Data visualization refers to the art of representing data or more accurately the insights begotten by analysing the data. Before we discuss further about the importance of data visualization, let us understand how data analytics works.

The analytics workflow and its necessity

An increasing number of companies across different industries are dependent on data analytics for decision making. This has a very simple reason. The number of companies providing similar services has grown in tandem with the number of consumers. The market is replete with choices for the consumers hence the competition is fierce. There is a risk of losing customers at every step. So the companies use data driven insights to modify their products and services and thus try to reduce the risk factor. The whole process of gathering, cleaning and analysing data is generally referred to as data analytics. Analysis happens in three steps.

  • Data collection is the first step. This data can be collected from the organizations’ transaction logs or from various platforms where customers create textual or transactional data.
  • Next step is usually data cleansing. This means segregating relevant data for a certain purpose.
  • Then comes analysing the data by putting it through certain models and algorithms.
  • Data visualization comes in the end. This means representing the analysis results through pictures, tables charts and graphs.

Why is visualization needed?

It is time to return to the original question about data visualization. We must remember that the key function of analytics is creating actionable insights. A data analytics cannot work alone, she has to create a communicative platform with the other sections of the company. The inferences made by the analyst have to be agreed upon by the company executives. Otherwise the whole process becomes meaningless. Data visualization creates this communicative platform shared by the analyst and the stakeholders.
