Add diagram to show delta lake - cluster - IDE relationship in Databricks

Is your feature request related to a problem? Please describe.
Working out what each thing is and does can be difficult so a diagram might make it clearer for people new to the platform

Delta lake: where the data lives and is structured
Cluster: what you use to connect your IDE to the data
Databricks: IDE / platform that allows you to interrogate or work with the data

Additional context

Worth making a comparator to SQL server before using SSMS and also R Studio

Think there's also something different here depending on how you're planning on using the data from the Delta Lake

So if using the Databricks platform/SQL editor in the browser it's
Delta Lake ⬅️ Cluster ⬅️ Databricks analysis platform

If using RStudio it's
Delta Lake ⬅️ Cluster ⬅️ ODBC connection ⬅️ RStudio
