In addition to visualizing networks, webweb allows users to color or size a networks nodes by metadata attributes, including scalar, boolean, and categorical values. Networks can be weighted or unweighted, and the stroke width of the network can reflect link weights via one of the html checkboxes in the interface. While all display options can be user-adjusted in the browser via the UI, all display option defaults can also be set from the Python or MATLAB code. Extensive examples and a complete list of API-accessible display options are provided on the documentation website. webweb is intended for network scientists who may or may not programmers. Its API is structured to support a wide range of inputs formats (edge lists, adjacency matrixes, vectorized and JSON-object style metadata), and it behaves intelligently when given ambiguous inputs.
