Step 5: Creating Dashboards

Tableau allows you to combine multiple visualizations into interactive dashboards. In this step, you'll learn how to create dashboards by arranging your visualizations, adding actions, and filters for user interactivity.

Step 6: Sharing Your Work

After creating your visualization and dashboard, you can share your work with others. Tableau provides options to publish your visualizations to Tableau Server or Tableau Online, or you can export them as image files or PDFs for sharing.

Step 7: Learning Resources

As a beginner, your Tableau journey doesn't end with your first visualization. To continue your Tableau education, explore the numerous learning resources available. Consider enrolling in a Tableau training course to deepen your skills and become proficient in data visualization and analysis.
