(Graph description language)

A “hierarchical” or layered drawings of directed graphs can be drawn easily by using this DOT. This is the default tool to use if edges of the graph are directional.

It is a tool which generates diagrams with less effort. A tool for lazy developer — to portray a simple diagram with a very less amount of effort and detail. Not similar to Paint

It carries a very less amount of code and syntax. All you need is to specify the nodes and the links

If you’re about to draw a graph, it is very easy to draw with DOT. No prior configurations… setups.. needed

Just open a text editor — write some lines of code — save as .dot file — graph ready

Lets see, how to do all with DOT!!!

Sample Code — 1

Save it as (filename).dot
