Display list of token on click

[EatingW]

Poker planning notes:

• If user clicks on a node they see a pop up with list of tokens.
• Metadata already part of the json graph data for displaying the graph.
  • cons of this approach: loading metadata too early might have too much data if there are lots of nodes with lots of metadata
  • pros: optimizes for if user interacts with this feature a lot
  • can consider this more in a followup
• Click again removes the pop up.
• Too much metadata might need scrollable pop up
  • Maybe clicking a close button to close the pop up instead?
• To be considered done:
  • Demo with clicking and displaying
  • Front end tests to verify the content of the pop up
