-------------------------------------------
VisJS looks good in terms of licensing to me (MIT/Apache dual). Looking forward
to your screenshot/PR.
> Topology Visualization revamp / swap underlying JS graphing library

> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-ui
> Reporter: Stephen Powis

> h4. Problem Statement
> Being able to visualize your topology is amazing. Unfortunately the current
> implementation for displaying the topology leaves a bit to be desired.
> Having the nodes in the graph floating across the screen while trying to read
> it is distracting and makings it difficult to read complex topologies.
> Additionally there are no real legends or on screen help/hints/documentation
> that explain what is being shown.
> h4. Proposal
> Re-implement how we display the topology using a different JS library that
> makes reading and understanding the graph significantly easier. Make use of
> the existing visualization APIs, but simply swap out the rendering library.
> Additionally provide a better key/legend/documentation around the
> visualization.
