var viewer = new Cesium.Viewer('cesiumContainer');
var wyoming = viewer.entities.add({

Wyoming is the 10th most extensive, but the least populous \
and the second least densely populated of the 50 United \
States. The western two thirds of the state is covered mostly \
with the mountain ranges and rangelands in the foothills of \
the eastern Rocky Mountains, while the eastern third of the \
state is high elevation prairie known as the High Plains. \
Cheyenne is the capital and the most populous city in Wyoming, \
with a population estimate of 62,448 in 2013.\
