We present an open source computational geometry framework with interactive visualizations. We provide code for simple topological data structures that can describe planar geometry, polyhedral surfaces, and even more complex topological surfaces. Because the data structures use the same simple primitives for all levels of complexity, it provides a natural springboard for students, educators, and developers. See compugeom.github.io for an interactive demo.
