The new Lookup Field feature in MongoDB Charts allows users to join data from two collections or sources within the chart builder, creating a single chart with just a few clicks. This enables finding deeper insights by leveraging more data in a single visualization, and empowers more robust insights. The feature makes it easier, quicker, and more intuitive to bring fields from a second data source into the chart builder, even for MongoDB Query Language (MQL) power users. With the Lookup Field, users can visualize fields from each dataset in a single chart, without needing to write code or queries, reducing the need for complex data architectures that include many tables of data referencing each other.
