In this project, you will create a comprehensive sales dashboard using Tableau. This project will help you apply the skills you've learned throughout the course, including data connection, visualization techniques, and dashboard creation. By the end of this project, you will have a functional sales dashboard that provides insights into sales performance, trends, and key metrics.

• Connect to a sales data source.
• Create various visualizations to analyze sales data.
• Combine visualizations into a cohesive dashboard.
• Add interactivity to the dashboard using filters and actions.

2. Drag and drop the visualizations created in Step 3 onto the dashboard canvas.
3. Arrange the visualizations to create a cohesive layout.
4. Add titles and labels to each visualization for clarity.

1. Add filters to the dashboard to allow users to filter data by region, product, or date.
2. Create dashboard actions to enable interactivity between visualizations (e.g., clicking on a region in the sales by region chart filters the other visualizations).

1. Review the dashboard to ensure all visualizations are clear and the interactivity works as expected.
2. Publish the dashboard to Tableau Server or Tableau Online for sharing with stakeholders.

1. Connect to the provided sales data source.
2. Create the following visualizations:
   • Sales over time (line chart)
   • Sales by region (bar chart)
   • Top products by sales (bar chart)
   • Sales by category and sub-category (stacked bar chart)
3. Combine the visualizations into a dashboard.
4. Add filters and actions to make the dashboard interactive.
5. Publish the dashboard to Tableau Server or Tableau Online.
