Tableau
Tableau is a popular software tool that helps people turn complex data into easy-to-understand visual charts, graphs, and dashboards. It's like PowerPoint for data, but much more powerful and interactive. Companies use Tableau to make sense of their business information, such as sales trends, customer behavior, or market analysis. The tool is especially valued because it allows people without technical coding skills to create professional-looking data visualizations and reports. Similar tools include Power BI and Qlik, which all belong to a category called "business intelligence" or "data visualization" software.
