title: Mapbox osm buildings extrude heights
body: <p>This example demonstrates extrusion of buildings polygons with constant height data: jsfiddle.net/yedg641a/</p>
  
  <p>Another example, on mapbox tutorial site, demonstrated extrusion based on height data from vector tiles.

  <p>Are there any possibilities to achieve this effect without using mapbox services, like example on js fiddle ?</p>
