Frequently Asked Questions
What is DOT language?
DOT is a graph description language. It uses a simple text syntax to define nodes and edges. For example: "A -> B" creates a directed edge from A to B.
Which layout engine should I use?
Use "dot" for hierarchical layouts, "neato" for spring model layouts, "circo" for circular layouts, and "fdp" for large undirected graphs.
Can I customize node and edge styles?
Yes, DOT supports extensive styling options including colors, shapes, fonts, and line styles. Use attributes like [color=red, shape=box].
Is GraphViz installed on my computer?
No installation needed. We use Graphviz compiled to WebAssembly, running entirely in your browser.
