 ## SELECT BLOCK
 1-Block SELECT is a feature that offers an exploratory (interactive style) approach to querying data in a style similar to SQL or Cypher. This syntax enables users to write a single, concise select-from-where-accum statement on one line to retrieve data based on specified conditions. It also supports operations such as filtering, aggregation, sorting, and pagination, making it an excellent tool for ad hoc data inspection.
