That is correct. WebGL outperforms HTML5 Canvas 2d context, and HTML5 Canvas 2d context outperforms SVG. With WebGL, you are loading up the vertices of all the nodes and edges into the GPU, and they stay there. All the transformations like panning and zooming happen on the GPU. El Grapho uses picking for hit detection via ConcreteJS, so hit detection is nearly instantaneous for any number of nodes and edges, i.e. millions of them.
