Custom chronograph visualizations/plugins

Hi, I have been exploring the TICK and ELK stacks. Kibana allows for the development of plugins and apps (like TIMELION, plus they list loads of other contributed apps/visualizations).

Does chronograph support custom visualizations or plugins as well. I couldn’t find documentation/blogs relating to this. Could someone help out by answering this or pointing me to the right resources please?

Thanks
