# Dimensions ## What is a dimension ? A dimension allows you to categorise your data. For example, imagine that you go grocery shopping (again!). We are buying tomato, so we can probably group our tomatoes by size, by color, by weight, and so on. These are dimensions, are they allow use to put our tomatoes into different groups. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
