If you receive the error: "Your configuration does not seem to support WebGL content. You may be using an unsupported graphics drive". It's quite likely that the GPU of your Chromebook is not supported by WebGL. In order to make sure this is not the case please try these WebGL examples: https://threejs.org/examples. Go to the "WebGL" section and email email@example.com if you receive an error or if any of the examples fail to appear.
