If you want realistic maps, some links which might be useful as a starting point:

@amellnik you are right on about this. plotly.js can do it, so PlotlyJS.jl can also. here are a couple examples from the PlotlyJS.jl docs

However a lot of what you seem to be describing is the GUI.
Julia is good at the number crunching to make the modelling work. While Julia is good at displaying data, I have thus far not found very good ways for user inputs. Some non-Julia GUI front-end linked to a Julia back-end might do the trick.

Maybe see here for some ideas for GUI options:

The warning is expected. There’s been a couple of fixes very recently, so you could try master (]dev Gtk), otherwise you can open an issue in the repo. Everything running without error but nothing showing is definitely strange.
