Which of the following is a common data visualization tool?

Tableau is a widely recognized data visualization tool that enables users to create interactive and shareable dashboards. It is specifically designed to help visualize and analyze data efficiently. Tableau allows users to connect to various data sources, perform complex calculations, and generate a range of visualizations, from simple charts to sophisticated graphs, making it an essential tool for data analytics.

In contrast, Microsoft Word is primarily a word processing application and is not designed for data visualization. While it can include charts and graphs, its primary function is text editing. Adobe Photoshop, while powerful for image editing, is also not focused on data visualization and lacks the specific features needed for analyzing and displaying data. Slack is a communication platform designed for team collaboration and messaging, and it does not have capabilities for data visualization. Therefore, Tableau stands out as the most suitable tool for this purpose.
