Cartographic anmations have evolved over time. In prehistoric histories the use of sticks, engraving in clay and drawing with charcoal dipicted animations of the people's interpretation in that particular time era.

"Isoline"

Isoline

An isoline map is a map with continuous lines joining points of the same value. For example points with equal elevation or points of weather commonality. The above map displays precipitation levels in 1996. If you look closely you can see that areas shaded light purple represent about 120 inches of rain, and blue about 20 inches. You can also correlate the darkening of colors with increasing rainfall.
