Docker: replace Chromium for drawing graphs ?

[bschmalhofer]

          The lightweight alternative to Chromium is to use node.js on the server. For examples how this can be done see:

• https://www.npmjs.com/package/d3-node (looks like this is not needed)

This needs to be discussed. The scope might be larger than just drawing some graphs, other items might have to be made printable as well.
