drawio-impl-csv-import

Generate Draw.io diagrams from CSV data by applying directive lines before the header row and running a CSV import to automatically create structured visual flows. This approach supports org charts, ER diagrams, networks, and process flows from tabular sources.

Draw.io CSV import directive lines are special metadata commands prefixed with # that define labels, connections, layout, identity, and ignored columns. They must appear before the header row to properly format data-driven diagrams and ensure correct JSON connections.

Draw.io CSV import fails when directive lines are missing, connection JSON format is incorrect, or %column% placeholders are invalid. Ensure directives are ordered before the header and validate JSON syntax in connect directives to prevent generation errors.

Yes, you can create org charts, ER models, networks, and process flows from CSV files. Apply identity and connect directives to map hierarchical relationships, enabling deterministic diagram generation from tabular data with auto-layout options.

The correct JSON connection format uses %column% placeholders to reference source and target columns within the # connect directive. Validating this JSON structure ensures deterministic relationships are established across nodes in the generated diagram.

Yes, Draw.io supports auto-layout options for data-driven CSV diagram generation. By applying the # layout directive alongside label and connect directives, you can automatically arrange nodes and edges for visually structured tabular data representations.
