Worksheet:
A worksheet is a single view or visualization created in Tableau. Each worksheet lets you drag and drop fields to create a variety of charts, graphs, and tables. Worksheets are the building blocks for dashboards and stories.

• Rows and Columns Shelf: Place dimensions and measures to structure your visualization.
• Marks Cards: Customize the appearance of data points.
• Filters Shelf: Apply filters to refine the displayed data.
• Pages Shelf: Create animations and split the visualization into pages.
  

Data and Analytics Shelf:
The Data pane contains all the fields from your connected data sources, organized into dimensions and measures. The Analytics pane provides tools for performing advanced analysis on your data.

• Data pane: Drag dimensions and measures to the shelf to create visualizations.
  • Dimensions: Qualitative data (e.g., categories, names).
  • Measures: Quantitative data (e.g., sales, profit).
    
• Analytics pane: Access tools for adding trend lines, reference lines, forecasts, and more.
  

Page Shelf:
The Page Shelf allows you to create animations and divide your visualization into separate pages. This is useful for showing changes over time or for categorical data.

To use the Page Shelf:

• Drag a dimension or measure to the Page Shelf.
• Tableau creates a separate page for each value in the field.
• Use the page controls to navigate through the pages.
  

Filter Shelf:
The Filter shelf is used to apply filters to your data, which refine what is displayed in your visualization. Filters can be applied to dimensions, measures, or the entire data set.

To add filters:

• Drag fields to the Filter shelf.
• Select criteria for filtering (for example, specific values, categories).
• Apply filters to adjust the visualization.
  

Marks Card:
The Marks card is a versatile tool for customizing the appearance of your visualization. It allows you to change the type of mark (e.g., bar, line, shape) and adjust the color, size, label, description, and tooltip.
