# Data Sources > Depth-first rabbithole dossier for Data Sources; source-anchored research pack. Parent: [MongoDB Atlas Charts](https://llms-explorer.com/tree/mongodb-atlas-charts/) · 5 facets · 17 facts · page: https://llms-explorer.com/tree/data-sources/ ## Structure and components - [low] The on-prem version of MongoDB Charts was discontinued in September 2021, and the only unsupported version is the on-prem version, while Charts remains supported as a component of Atlas and must be used with MongoDB Atlas. (verified as of 2026-10-15) Sources: https://www.mongodb.com/community/forums/t/is-mongodb-charts-discontinued/144944 — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` ## How it works - [low] If external sharing requires authentication, any chart using the data source requires SSO for external viewing, and users can only view charts on dashboards when logged into Atlas Charts, not via public links. Sources: https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` ## Problems, failure modes and limitations - [medium] Charts automatically includes the Sample Data: Movies data source in all Charts tenants, which cannot be added to, edited, deleted, removed, or used in externally shared or embedded charts. Sources: https://www.mongodb.com/docs/charts/data-sources.md, https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` - [low] If you disconnect a database in MongoDB Atlas Charts, Charts disconnects all of the data sources in that database, causing any charts that use the data source or access it via $lookup to no longer render and display an error. Sources: https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#troubleshooting` - [medium] To apply a pipeline in MongoDB Atlas Charts, you must use a charts view, as pipelines cannot be applied to an entire collection, and the Pipeline option is dimmed for collections. Sources: https://www.mongodb.com/docs/charts/data-sources.md, https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` ## Comparisons and alternatives - [low] MongoDB Charts provides fast, native dashboarding directly inside MongoDB Atlas with limited customization and analytics compared to full BI platforms, while MongoDB Data Explorer offers quick schema exploration and simple visual queries with basic dashboards only. Sources: https://hevodata.com/learn/mongodb-visualization/ — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` ## Facts and statements - [medium] Atlas Charts connects to all deployments and data sources in your project by default, including all clusters for which you have the Project Data Access Read Only role or higher, and all federated database instances in your project, including Online Archives. Sources: https://www.mongodb.com/docs/charts/data-sources.md, https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` - [low] An Atlas Project Owner can connect or disconnect data sources and deployments, and a deployment and its data sources will not display on the Select Data Source modal unless they are connected to Charts. Sources: https://www.mongodb.com/docs/charts/data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` - [low] To combine two or more data sources in MongoDB Atlas Charts, you must create an Atlas Data Federation. Sources: https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` - [low] To share a chart externally via embed or link, you must enable external sharing on both the data source and the individual chart, as Charts disables external sharing by default for all data sources. Sources: https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` - [low] Organization-wide sharing grants users in your organization, including non-project members, permission to view data in a deployment used for dashboards shared with your organization. Sources: https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` - [low] If external sharing does not require authentication, any chart using the data source can be viewed on dashboards shared via a link, and embedded charts can render using both unauthenticated and authenticated requests. Sources: https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` - [low] Charts automatically assigns project roles to users based on their Atlas user role, and already authorizes data source permissions to view and create charts for Project Owner and Data roles. Sources: https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` - [low] To modify a data source's read preference in MongoDB Atlas Charts, you must modify the read preference for its deployment. Sources: https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` - [low] If you turn off external sharing for a data source, all charts which use that data source stop rendering immediately. Sources: https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#troubleshooting` - [low] Charts does not display the Version for federated database instances. Sources: https://www.mongodb.com/docs/charts/manage-data-sources.md — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/data-sources-fee47c958a/rabbithole-synthesis.md#core` - [low] MongoDB Compass is suited for developers and DBAs needing visual schema view and query debugging, but is not suited for executive dashboards or team collaboration.
