Tableau Public is a free data visualization tool that can help you to see and share insights in your data without programming knowledge. The visualization can be shared online or downloaded to your device. Do take note that the completed visualization work and data in Tableau Public are to be made freely accessible to everybody. As a result, we do not recommend you to use this tool if your data involves sensitive information.
We use this Excel file which contains data of CO2 emission from the World Bank to demonstrate how Tableau Public can help us to visualize our data. You may also find more tips from the official video tutorials directly.
