Did not know about Tangram, seems awesome!<p>I have a (dumb) question. Why do you use Leaflet? Isn't Tangram the same as Leaflet, or am I missing something here?<p>A fully WebGL mapping solution is better for performance, but won't using Leaflet HTML5 Canvas defeat this purpose?<p>It seems to me that, because of this, Mapbox GL will have a better performance than Tangram.
