The Tableau data visualization process involves four key steps:
1. Connecting to Data: This is the first step in the Tableau data visualization process. Here, the user connects Tableau to the data they want to visualize. This can be done by connecting to a file, like an Excel or CSV file, or by connecting to a database.
2. Preparing the Data: After connecting to the data source, the user needs to prepare the data for analysis. This involves cleaning the data, creating calculated fields, and creating groups and hierarchies.
3. Visualizing the Data: In this step, the user visualizes the data. This can be done by creating charts, maps, scatter plots, and other visualization types.
4. Interacting with the Visualization: Finally, the user can interact with the visualization to gain insights. This includes filtering, drilling down, and exploring the data.
For example, a user might want to visualize sales data from a retail store. They would first connect to the data source, which could be an Excel file or a database. Then, they would prepare the data by cleaning it and creating calculated fields. After that, they would create a visualization, such as a bar chart, to show the sales figures. Finally, they would interact with the visualization to gain insights, such as which products are selling the most.
