Improve the visualization of the SVG graph

[rishinair11]

Instead of a static SVG, it would make sense to make the children nodes collapsible, so that only the required nodes are displayed.
This will improve the legibility of the graph.

A search functionality would also be nice, over the node names, would definitely improve the speed at which important Flux and Kubernetes resources can be looked up and their parents and children can be observed.

This can be done in 2 ways:

• by templating an HTML file
• by using a JS library like React or Vue or some other library that supports fast static JS rendering.
