Dashboard setup

In this exercise, you will experience how to set up the foundation for building a comprehensive dashboard in Databricks as a consultant at Data X. The curated dashboard dataset is built from airbnb_combined (the cleaned Chapter 1 table, which is pre-provisioned for new sessions). If you are returning after a break, confirm that table is available before defining the dashboard dataset. Your task is to create a dashboard environment, define the dataset, and ensure it is ready for visualizations that provide meaningful insights.
