The vector stencils library "Sentence diagrams" contains 18 shapes for drawing sentence diagrams or parse trees.
"In pedagogy and theoretical syntax, a sentence diagram or parse tree is a pictorial representation of the grammatical structure of a sentence. The term "sentence diagram" is used more in pedagogy, where sentences are diagrammed. The term "parse tree" is used in linguistics (especially computational linguistics), where sentences are parsed. The purpose of sentence diagrams and parse trees is to have a model of the structure of sentences. The model is informative about the relations between words and the nature of syntactic structure and is thus used as a tool to help predict which sentences are and are not possible."

The shapes example "Design elements - Sentence diagrams" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Language Learning solution from the Science and Education area of ConceptDraw Solution Park.

A Sentence Diagram is a pictorial representation of the grammatical structure of a natural-language sentence.
Diagramming sentences is a way to visualize how the different parts of a sentence fit together: the subject of a clause goes in one slot, the verb in another, and so on. Words that modify another word are attached to the word they modify. Understanding the functions of parts of the speech in a sentence and their relationship to one another can be very helpful in learning to construct good sentences.
The diagram of a sentence begins with a horizontal line called the base. The subject is written on the left, the predicate on the right, separated by a vertical bar which extends through the base. The predicate must contain a verb, and the verb either requires other sentence elements to complete the predicate, permits them to do so, or precludes them from doing so. The verb and its object, when present, are separated by a line that ends at the baseline.
For example, let's consider the following sentence: James bought a new book and gave it to his little sister. So, we see such parts of a sentence:
- James is the subject;
- bought a book and gave it are the compound predicate with direct objects (book, it);
- his sister is the indirect object;
- new, little are adjectives.
