About GV
Graphviz draws graphs from text. Programs write their dependencies, call graphs, state machines, database schemas and network maps in DOT, the language Graphviz reads, and save it as .gv or .dot for someone to look at.
A .gv file names nodes and the edges between them, with attributes for their shapes, colors, labels and ranks, and clusters that box nodes together. It says what's connected and how it looks, not where: Graphviz's layout engines, dot for layers, neato and fdp for springs, circo for circles and twopi for rings, place everything when it's drawn.
Filepeek lays it out in your browser with Graphviz itself, built for WebAssembly as Viz.js builds it, with the engine the file asks for. The graph opens sharp at any zoom, Search finds any label, and Export saves it as SVG, PNG or PDF. A .dot whose first statement is a graph opens the same way, while any other .dot is a Word template.

Questions
How do I open a .gv or .dot file?
Drop it on this page or press Peek a GV. It's laid out and drawn in your browser, on any computer or phone, with nothing to install.
Is a .dot file a graph or a Word template?
It can be either. Filepeek reads the start of the file: a graph or a digraph opens as its graph, and a Word template opens as a document.
Which layout does it use?
The one the graph's layout attribute names, or dot, Graphviz's own default, when it names none.
How do I convert DOT to PNG, SVG or PDF?
Open it, choose Export, then Save the page as SVG, Save as PDF, or save it as PNG or JPEG at 1x, 2x or 3x.
Can I edit it?
It's plain text, so any editor changes it.
