About This Tool

The DGML Viewer analyzes graphs defined in DGML by parsing the DGML XML, extracting nodes and links, and assembling an internal graph model. It computes a readable layout and renders an SVG representation that preserves connectivity and hierarchy where possible. The tool targets software engineers, data architects, and system analysts who need to verify graph structure, assess relationships, and produce shareable visuals for documentation. Unique value lies in deterministic rendering for identical inputs, quick validation feedback, and a lightweight, no-edit visualization workflow. Core features include DGML XML parsing, graph construction, layout rendering, and metadata reporting such as node and edge counts. Optional capabilities cover layout hints via DGML attributes, grouping by category, and filtering edge visibility to focus on specific relationships. The tool emphasizes correctness, reproducibility, and fast turnarounds for DGML-driven diagrams. Use cases include architecture reviews, data lineage tracing, and DGML-driven monitoring diagrams. The output is an SVG visualization plus quantitative metadata suitable for technical docs and knowledge bases.

Review the rendered SVG and read node/edge counts and any validation messages.
If needed, adjust DGML attributes and re-run to refine the visualization.

Frequently Asked Questions

Find Quick Answers

What is DGML and what does the viewer show?

DGML is a Graph Markup Language used to describe directed graphs. The viewer parses DGML, builds a graph model, computes a layout, and renders a scalable SVG that highlights nodes, links, and connectivity for analysis and documentation.

What data formats are supported?

The tool supports DGML as the input format. It expects a DGML Graph with Node and Link elements. Other XML formats are ignored unless they adhere to DGML structure. Validation reports indicate any structural issues.

How does it handle large graphs?

Large graphs are parsed and rendered in a deterministic manner with performance safeguards. If graphs exceed practical limits, the tool returns partial rendering and a detailed validation_errors message that indicates component size or complexity limits.

Can I export results?

Yes. The tool provides a rendered SVG string and metadata such as node_count and edge_count. The SVG can be reused in documentation or further processing; there is no file system export beyond the SVG content.
