Canvas

The canvas is Seaquel’s signature feature — an infinite visual workspace where you build analysis pipelines by connecting nodes together. It’s powered by XYFlow and designed for exploring data interactively.

Node types

The canvas supports four node types that chain together into pipelines:

• Table nodes — display table metadata including columns with types, nullability, defaults, primary key and foreign key indicators, indexes, and row count.
• Query nodes — SQL editor nodes with a name, SQL text, execution state, and execution time.
• Result nodes — display query output with columns, rows, and pagination. Connected to a query node.
• Chart nodes — visualize results as charts. Connected to a result node.

Building a pipeline

1. Drag a table from the schema browser onto the canvas to create a table node.
2. Add a query node and write SQL referencing that table.
3. Execute the query — a result node appears automatically with your data.
4. Add a chart node connected to the result to visualize the output.

When upstream data changes, all downstream nodes update automatically. Edit a query and re-run it — the result and chart nodes refresh in place.

Working with the canvas

• Pan: click and drag the background, or use two-finger scroll.
• Zoom: pinch to zoom or use the zoom controls in the toolbar.
• Connect nodes: drag from a node’s output handle to another node’s input handle.
• Move nodes: click and drag any node to reposition it.

Note

Canvas state saves automatically and persists across sessions. Your workflows are always where you left them.

Use cases

• Build multi-step analysis workflows visually
• Compare results across related queries side by side
• Create reusable dashboards with charts that update on demand
• Explore unfamiliar schemas by dragging tables onto the canvas and inspecting their structure
