I figured I could use livebook to generate some sequence diagrams via plantuml.
The idea is that I have sequence diagram specification in another editor open and livebook repeatedly runs
plantuml ... command and displays the resulting .svg file.
However, I am not sure how to do that.
I can either display a static picture once with
Or I can display an updating chart with
Kino.VegaLite.periodically(widget, ...) but I can’t see how I can put a picture in the widget. Only graphs.
How can I make livebook display refreshed picture?
