Tableau software is a data visualization software that is used for visualizing data in an interactive and attractive way to understand the insights gained from large a pile of data. Tableau software is used in the domain of data science and business intelligence as the software provides quick wide-ranging visualizations within few clicks and could handle large amounts of data without a performance drop.
