Graph visualisation

[macjuul]

This PR implements graph visualisation of records as a new display mode for Query View responses.

Features

• Visualise any supported query response as a graph
• Automatic force based physics layout
• Control appearance by hiding tables, edges, and individual nodes
• Right-click nodes for actions such as opening the inspector, hiding visibility, and expanding relationships
• Expand node relationships to append all neighbouring nodes to the graph

Response visualisation

In order for Surrealist to build a graph, it will recursively analyse the query response to collect a list of all referenced record IDs. These are sent back to the database to discover all relationships between this subset of records.

Table & edge filtering

The integrated sidebar allows you to toggle the visibility of tables and edges. Doing so will immediately update the graph, causing nodes to slowly re-arrange themselves where necessary.

Record expansion

When a record context menu is opened, Surrealist will query all direct record relations which are not yet represented in the graph.

Appearance options

There are two additional settings provided to fine-tune the graph for visual clarity, which is the ability to show stray records (records with zero relations), and the ability to collapse edges into straight lines.
