JPowerGraph is a Java library for creating directed graphs for both Swing and SWT. It supports graph movement, selection, context menus, tooltips and dynamic edge creation. JPowerGraph has a spring layout algorithm based on that used in TouchGraph.
TouchGraph provides a set of interfaces for graph visualization using force-based layout and focus+context techniques. For now only older code is available, but we are planning to release new versions as well.
Auth0 Token Vault handles secure token storage, exchange, and refresh for external providers so you don't have to build it yourself.
Rolling your own OAuth token storage can be a security liability. Token Vault securely stores access and refresh tokens from federated providers and handles exchange and renewal automatically. Connected accounts, refresh exchange, and privileged worker flows included.
