CZML Polygon
- "polygon":
{ "positions": { "cartographicDegrees": [lon0, lat0, h0, lon1, lat1, h1, ...] }, "material": { "solidColor": { "color": { "rgba": [r,g,b,a] } } }, "height": <number>, "extrudedHeight": <number>, "show": true|false } — a filled, closed shape over the ground.
"positions" defines the corners in order; the polygon is implicitly closed (do not repeat the
first point at the end). Use a translucent "rgba" alpha (e.g. 128) for a semi-transparent fill.
Example: a filled rectangular area of interest
