Hello

Below is the kind of maps I would like to draw.  
The colors would be changing according to some data.  
I would dream of making animated gif files on this basis.

Any idea how I coul proceed?

Thanks

Michel

GMT.jl can be used for this. See for instance the [`coast()` function doc](https://github.com/GenericMappingTools/GMT.jl/blob/master/docs/src/coast.md).

One quick example using GMT.jl:

Is this possible with VegaLite.jl and Vegadatasets?

@Mastomaki, there is [one example here](https://discourse.julialang.org/t/how-to-change-the-country-name-and-then-draw-the-global-map/88076/20) that could be a good starting point.
