I'd like to use a newer version of Graph.JS

Found the simplest solution:

  1. Add dashboard template widget to Node-RED flow
  2. Edit properties and set Template type to Added to site <head> section
  3. paste <script src="https://cdn.jsdelivr.net/npm/chart.js@3.7.0/dist/chart.min.js"></script> into template node

It overwrites the v2.3 Chart.JS namespace and my chart displays as expected :+1:
