DotChart for DOT and Graphviz

DotChart is designed exclusively for previewing and editing DOT and Graphviz graphs. Start with a built-in template to instantly create finite automaton, entity relation, trees, and more. Or begin with a blank document to write your own graph from scratch. DotChart can also be used in combination with an external editor, graphs automatically update when changes are made.
DOT is a graph description language used to define diagrams, and DotChart lets you render these graphs. The DOT language can be used to describe an undirected graph that shows simple relationships between objects, such as the following example:
graph graphname {
a -- b -- c;
b -- d;
}
The language can also describe directed graphs, such as flowcharts and dependency trees, as shown in the following example:
digraph graphname {
a -> b -> c;
b -> d;
}
