 - make an blank scatter plot for the colorbar.
 - use a dedicated space in the layout for the colorbar.

 In the VSCode plot panel and https://github.com/fredrikekre/Literate.jl notebooks, PNG images are generally smaller than SVG ones. To force plots to be shown as PNG images, you can use https://github.com/tkf/DisplayAs.jl to show objects in a chosen MIME type.

 `sqrt(x)`, `log(x)`, and `pow(x)` will throw `DomainError` exceptions with negative `x`, interrupting differential equation solvers. One can use these functions' counterparts in https://github.com/JuliaMath/NaNMath.jl, returning `NaN` instead of throwing a `DomainError`. Then, the solvers will reject the solution and retry with a smaller time step.

 Some tips about https://github.com/JuliaPy/PyPlot.jl, the `matplotlib` (Python) visualization library for Julia. See also [docs for matplotlib](https://matplotlib.org/) since `PyPlot.jl` largely follows `matplotlib`'s API.
