No other sector is more dynamic than the field of Information Technology. Professionals working in this area know how new languages, tools, and techniques continue to emerge and create a more vigorous competition in the market. Undoubtedly, artificial intelligence and data science are two of the prominent technologies that have grabbed the attention of companies worldwide. Data has become more important than ever, and data-related job positions are commanding far higher salaries than software developers.
Data visualization is one of the steps involved in data science. Raw data is first gathered, stored, managed, and analyzed to draw meaningful insights from it. The analyzed data is then visualized through graphs, charts, or dashboards so that the correlations can be easily communicated to the stakeholders. Now, there are various tools that offer powerful data visualization features and dominate the entire market. The leader among all of the data visualization tools is Tableau.
