Open a tool, paste source content, choose an example when useful, and review the preview pane for output or syntax errors.

Supported tools expose copy, SVG, PNG, and print-style PDF actions when the renderer can provide them.

If a diagram does not render, reduce the source to a smaller example, check the syntax for the format, and then add sections back gradually.

For PlantUML, the first version uses a PlantUML server URL, so network access to that endpoint may affect previews.
