Dear Sir, That's a really good display! I was wondering is it possible to change the color of backround (currently it's default black) without changing the point color, and the shape of the data points (currently it's square)? Thank you very much!

Thanks, and sorry for the late response! To change the background color, you can add the following line: `scene.background = new THREE.Color(0xff0000)` (to set to red, for example). Changing the shape of the points is a bit more involved. You'll need to use sprites -- an example can be found here: https://threejs.org/examples/#webgl_points_sprites.
