The shaded relief technique is a method for representing the topography which is prettier and intuitive.
I found some examples about doing them with d3js, but required a previous preparation with gdal. I wanted to show how to create the effect using the DEM file directly. I added the tutorial to the d3-raster-tools-docs tutorial.
The result:
