## Description

JSON Canvas is an interoperable whiteboard specification and data exchange format. It provides a standardized JSON schema for representing nodes, edges, and spatial layout information, allowing different infinite canvas and digital whiteboard applications to read and write the same files.

The project focuses on digital whiteboard interoperability and spatial data standardization to prevent vendor lock-in. By using a coordinate-based layout mapping and a machine-readable format, it enables cross-platform visual mapping and the migration of spatial data between different software environments while maintaining layout integrity.

The specification covers a broad capability surface including data integration, the conversion of canvas formats, and the standardized storage of spatial canvas data.
