Overview
--------

[](#overview)

`tc-lib-pdf-graph` implements low-level drawing operations used to build PDF graphic content.

It exposes the primitives needed to compose paths and painting operations while keeping the API close to PDF graphics operators. This makes it suitable as a foundation layer for charting, vector drawing, and custom layout engines.
