Fill areas with various line density to offer roughly visible consideration. With geographic maps, the method is particularly helpful to regulate for inhabitants density.

However I’ve been coming again to the tactic recently. In some circumstances, it’s been helpful and others I feel it simply seems to be good and gives a break from our commonplace, visually environment friendly charts.
Most not too long ago, I used hatching to indicate inhabitants density and commute instances.
