Tableau is a data visualization tool that helps to create an interactive dashboard that helps the stakeholders to make business decisions.
Tableau helps to create charts and graphs with our data which can be provided from databases. These charts and reports can be understood by the stakeholders easily.
The tableau does not require much coding or programming skill, it requires the skill of storytelling with visualization. The tableau helps to convert complicated data into digestible reports and dashboards which can be then used to make decisions. The whole concept of the tableau is that it can make data into a visual format so that it becomes easier to make decisions based on data.
Tableau has become an important tool for business and finance as there is a lot of data that is generated by the users. For the stakeholders, this data is completely meaningless until some analyst uses data visualization to convert this data into an understandable format.
