General Considerations
The software which generated these images consists of a series of JavaScript modules, one for each type of image: drop, partition tree, grid, and lines. Each module exports a function that adds the relevant set of methods to a JavaScript object. For each individual image, a "generator" loads the needed modules and applies their method-defining functions to an object which it creates, sets the parameters for that image, and finally, applies the top level image generation methods one or more times.
The software includes base capabilites, regardless of the image modules loaded. These include methods for manipulating geometry and "shapes". A shape is a JavaScript object which includes a link to an SVG representation used for its display.
