Cosmograph web application

Cosmograph is a workspace for loading graph or embedding data, configuring an interactive visualization, exploring its structure, and sharing the result with others.

This guide covers the current application workflow. Use the focused guides for Sharing, Discussions, Plans, and AI Assistant when you are ready to collaborate or use paid features.

Start a graph

Open Cosmograph and select New graph from the Graphs page. You can work on a graph before signing in, but sign in to save it to your account.

Saved graphs appear in Graphs. That page separates graphs you own from graphs shared with you directly or through a team.

Add data

Use the data setup screen or the Data Sources panel to add your graph data. Cosmograph accepts these uploaded file formats:

• CSV and TSV
• JSON and NDJSON
• Parquet and PQ
• Apache Arrow

For a network graph, add a links table and map its source and target columns. You can also add a points table with a unique ID and optional properties such as labels, colors, sizes, or coordinates.

For an embedding, add a points table with an ID and coordinate columns. Additional columns can be used to style, label, group, filter, or inspect points.

Configure and explore

The project panels keep the main workflow close to the graph:

• Data Sources: add files, review tables, and map graph columns.
• Graph configuration: control point and link appearance, labels, and simulation settings.
• Filters, Search, and Dataset Tables: focus on a subset of the data and inspect the rows behind it.
• Assistant: ask questions about the loaded data, create supporting charts, or select matching points on the graph.
• Discussions: leave feedback on the project, a point, or a graph location when you have project access.

Save your work

Use Save to Cloud or Sync changes in the top bar to save a graph. Free accounts can keep working on unsaved graphs; saved-graph limits and current plan actions are shown in the app. Pro and Team plans include unlimited saved projects.

Share and collaborate

The Share… menu lets an owner publish a read-only graph, protect a published graph with a password, share directly with a registered user, or share with a team.

Published and shared graphs are read-only for viewers and non-owner collaborators. They can explore the graph and, when authenticated with project access, participate in Discussions, but they cannot change, save, or re-share the owner’s source project.

Read Sharing before publishing data or granting access. It explains which sharing option fits each audience, what access it provides, and how to revoke it.
