+# plexus
+
+plexus is a React component for rendering directed graphs.
+
+## Why?
+
+To support directed graphs in Jaeger-UI, we surveyed the JavaScript libraries and utilities available for rendering directed graphs. The landscape is impressive, but we concluded the venerable [GraphViz](https://graphviz.gitlab.io/) ([alt](https://www.graphviz.org/)) is the right tool for us.
+
+GraphViz is awesome, but the output formats don't fit our needs. We've elected to use GraphViz to generate the layouts (node positioning, edge routing) and React for rendering.
+
+## viz.js
+
+The excellent [viz.js](https://github.com/mdaines/viz.js) is used, in a WebWorker, to generate GraphViz as plain-text output which is then parsed and provided to a React component which does the rendering.
