Time Dynamic Width and Color


I am trying to use the d3Cesium source code to visualise some time dynamic values on the globe. I was able to change the height of the polyline with time dynamic data, but the width and color seems to remain fixed. Even in the d3Cesium code the width seems to be fixed. Is it possible to change the width of the line , Also it would be great if I can change the colors as well.

One more question, Instead of line can I insert a cylinder instead. I would like to change the height, color and width of the cylinder. Just let me know whether it is possible or not, that should be sufficient.
