I'm trying to create something similar to the D3+Cesium demo (https://github.com/abwood/d3cesium) for a project I'm working on.
I'd like to draw some vertical bars, with their length varying depending on the time.
- How can I define variable length "lines" like the ones in the D3+Cesium demo in a CZML file? Can somebody give me an example?
- How can I adjust the time interval of the "timeline" (the bottom control in the viewer) just to display a few years (in order to control the animation defined in the CZML file?).
