Hello. Is there a way change the fill color with expression based on a number? Let’s say you want -50 be blue, 0 to be white and 50 to be orange and I want to link them to a slider or something so I will be able to change the fill based on the number I put in.Thanks.

I'm not sure i entirely understand your question, but I think you're looking for the expression that I have on the color fill which links the color to the slider number here:
var slider = effect("Country Slider")("Slider");
var c1 = thisComp.layer("Color Control").effect("Start color")("Color");
var c2 = thisComp.layer("Color Control").effect("Mid color")("Color");
var c3 = thisComp.layer("Color Control").effect("End color")("Color");
if (slider < 100000){
ease(slider,0,100000,c1,c2);
} else {
ease(slider,100000,1000000,c2,c3);
}

Can you please give a complete tutorial to produce such a map animation?

The map was created in Geolayers 3 plugin. You could also use any vector shapes, if you have a vector map just use that.
