The latest update to MongoDB Charts, now available as part of MongoDB Atlas, provides new data exploration features that allow users to view the source documents, aggregation pipeline, and transformed data underpinning a chart. These features include three options: View Source Documents, View Aggregation Pipeline, and Get Chart Data, which provide insight into how Charts is transforming the original data. Additionally, other new features include the ability to change field data types while building charts and the freedom to place charts across the full width of a dashboard on large screens.
