The graphviz.notation vocabulary provides words for building graphs in a way that looks similar to the DOT language (see https://graphviz.org/content/dot-language).
The graphviz vocabulary alone already follows the general structure of the DOT language: graphs and subgraphs consist of an ordered sequence of statements; each statement will add either a node, an edge, or some attribute declaration (graph-attributes, node-attributes, edge-attributes); and attributes may be set on individual nodes and edges. Even some DOT niceties are already supported, like being able to have an edge between anonymous subgraphs. For instance, compare
with the DOT code
However, there are some rough points that this vocabulary addresses:
Notation for setting Graphviz attributes
Aliases that resemble DOT code

with the DOT code
digraph {
{ 1 2 3 } -> { 4 5 6 }
}
