Interactive GraphViz DOT Editors: yEd, qvge & Online

Yes — there are interactive GraphViz editors that import GraphViz DOT and let you drag nodes, reposition them, and edit connections. For a reliable DOT round‑trip use desktop tools like yEd or the Qt Visual Graph Editor (qvge); for quick browser edits try the Graphviz Visual Editor or Edotor, and for embeddable/custom interfaces look at d3-graphviz. Cytoscape (and tools like Gephi) can load DOT for analysis but typically aren’t the best choice when you need precise, exportable DOT with preserved node positions.

yed graph editor: Desktop DOT import & round-trip editing

If you want a desktop application that reliably imports DOT, lets you move nodes freely and exports back to DOT, start with yEd. yEd imports GraphViz DOT via File → Import → GraphViz DOT and converts the graph into editable objects you can drag, relabel and style; it also offers automatic layouts that will respect manual adjustments. When you export, yEd can write a GraphViz DOT file again (File → Export → GraphViz DOT) so you can preserve your edits for further GraphViz processing or version control. See the yEd product page for details and the import/export flow: https://www.yworks.com/products/yed.

Why choose yEd? It’s cross‑platform (Java), user-friendly, and good at keeping a usable DOT export. Downsides: some GraphViz‑specific attributes or complex HTML-like labels may be converted or flattened during import/export, so always test a full round‑trip on a representative file before committing a large project.

qt visual graph editor (qvge) and desktop Graphviz editors

The Graphviz resources list several desktop editors that support DOT round‑trips; the Qt Visual Graph Editor (qvge) is one of them. qvge can import and export DOT, GEXF, GraphML and GML, and it provides drag‑and‑drop editing of node positions and edges. The Graphviz resources page summarizes available editors and workflows: https://graphviz.org/resources/.

Historical/packaged tools exist as well: the Graphviz ecosystem also includes GUIs that combine a text editor and viewer—useful if you want tight control over the DOT text while seeing rendered output. For basic interactive editing with DOT import/export, qvge and similar desktop GUIs are the most straightforward choice.

graphviz online editor options (Graphviz Visual Editor, Edotor, d3-graphviz)

If you prefer to edit in the browser, there are several workable options.

• Graphviz Visual Editor (web): listed on the official resources page as a DOT ↔ SVG editor that supports drag‑drop node positioning and edge editing. That DOT↔SVG workflow makes quick edits convenient when you just need to tweak layout or labels. See it on the Graphviz resources page: https://graphviz.org/resources/.
• Edotor: an interactive web UI for dragging nodes and editing edges; primarily oriented toward SVG output (good for visuals, less guaranteed for DOT fidelity). See the Graphviz resources page for a pointer: https://graphviz.org/resources/.
• d3-graphviz: a JavaScript library (covered in modern DOT toollists) that renders DOT via d3 and can provide animated transitions and interactive manipulation. It’s excellent when you want to build a custom editor or embed editable visualizations in a web app, but you’ll likely need to add code to serialize edits back to clean DOT. Reference: https://en.wikipedia.org/wiki/DOT_(graph_description_language) (modern tools mention d3-graphviz).

Quick note: browser editors are great for fast, visual tweaks and demos. But some web tools export only SVG, which becomes a flattened image (text converted to paths, etc.) and is not a clean DOT round‑trip. If you need a trusted DOT output, prefer apps that explicitly offer DOT export.

There are also community projects and small utilities that do exactly what you describe (interactive edits reflected back into DOT text). For example, a community-built editor that edits DOT text live while you move nodes is discussed here: https://www.reddit.com/r/foss/comments/1nn8gy9/i_made_a_simple_tool_for_graphically_editing/.

Cytoscape, Gephi and analysis tools — when they help and when they don’t

Tools like Cytoscape are powerful when your focus is analysis, attribute‑based styling, clustering or biological networks. Cytoscape imports standard formats (GraphML, GML, SIF) and can accept DOT via conversions, but it doesn’t emphasize a clean DOT round‑trip or preserving every GraphViz attribute; it’s built around analysis and visual mapping rather than faithful DOT editing and re-export: https://cytoscape.org/.

Gephi can bring DOT files in too (often via import plugins or intermediate formats), but many people find it better suited to exploratory layouts and statistics than to editing and exporting precise DOT files with preserved node coordinates. In short: pick Cytoscape/Gephi when you want analysis; pick yEd/qvge when you want editable DOT that stays DOT.

Practical workflow & tips for editable DOT round-trip

A simple, reliable workflow that most people use:

1. Back up the original DOT file (version control helps).
2. Import the DOT into a DOT-aware editor (yEd, qvge, or a Graphviz web editor that supports DOT import). The Graphviz resources page recommends opening DOT → drag nodes → re-run layout → export back to DOT: https://graphviz.org/resources/.
3. Make manual edits—move nodes, add/remove edges, change labels or styles.
4. Export back to DOT and inspect the file for pos attributes (positions) and any missing GraphViz-specific attributes. Look for lines like node1 pos="123,456" in the exported DOT if you need fixed coordinates.
5. If you want Graphviz to respect manual coordinates on subsequent renders, ensure your DOT includes positions and use the appropriate Graphviz layout engine/options that accept fixed coordinates. (Different engines treat pos differently; test on a copy.)
6. If the tool only exports SVG, use that for visuals but don’t expect a clean DOT round‑trip—SVG is primarily for final graphics, not for further DOT processing.

Extra tips:

• Test round‑trips on a small portion of your graph first.
• Keep style metadata (colors, HTML labels) documented; some editors convert or drop complex label markup.
• If you need an embeddable editor (for example, in a web app), use d3-graphviz and add a routine to serialize the current node positions back into DOT text.

Which editor should you choose? Quick decision guide

• Need a faithful DOT import → edit → DOT export with preserved positions? Use yEd or qvge.
• Want quick, throwaway browser edits or an interactive demo? Try Graphviz Visual Editor or Edotor.
• Building a custom web editor or embedding editing UI? Use d3-graphviz and implement serialization.
• Doing heavy network analysis, attribute mapping or clustering? Use Cytoscape or Gephi, but plan to export to GraphML/GML and accept limited DOT fidelity.
• Unsure? Start with yEd: it’s fast, user-friendly and explicitly supports GraphViz DOT import/export (so you can see whether your specific DOT features survive the round‑trip): https://www.yworks.com/products/yed.

Conclusion

Yes — interactive graphviz editors that accept GraphViz DOT and let you edit node positions and connections do exist. For dependable, editable DOT round‑trips pick desktop tools like yEd or qvge; for quick browser tweaks use the Graphviz Visual Editor or Edotor; and if you need embed‑ready interactivity choose d3-graphviz and add DOT serialization. Whatever you pick, keep the original DOT and test a full import → edit → export cycle so you know which GraphViz attributes survive the process.
