A simple javascript plotting boilerplate for 2d stuff.

/**
 * @author   Ikaros Kappler
 * @date     2018-08-27
 * @modified 2018-11-28 Added the vertex-param to the constructor and extended the event. Vertex events now have a 'params' attribute object.
 * @modified 2019-03-20 Added JSDoc tags.
 * @modified 2020-02-22 Added 'return this' to the add* functions (for chanining).
 * @modified 2020-03-23 Ported to Typescript from JS.
 * @modified 2020-11-17 Added the `click` handler.
