Programmatically create grapetree visualizations

[crarlus]

Hi,
thanks for grapetree, we use it a lot by uploading a mstree and metadata to a local grapetree instance in the browser.

However I wonder whether it is possible to create the grapetree visualizions (i.e. the json file) programmatically from the command line?

For instance, is there any such option as
grapetree --json --treefile mstree.nwk --meta metadata.tsv > grapetree_viz.json
?

This would be really helpful for updating the visualization whenever new data is available.

I agree. This type of command would be very useful! As great as the interactive program is, it can be laborious when I have to generate multiple MSTs with different subsets of data, node colors, etc.

I agree, too. Another nice feature would be the preloading of a json file before launching the local browser instance.

I came looking for this!! I would like this feature too. I'll bet that the hangup is that it is programmed in javascript instead of python. Maybe somewhere in here. I think it would be a great addition to bring it into the command line. https://github.com/achtman-lab/GrapeTree/blob/master/static/js/tree/d3_m_tree.js

Can anyone find the relevant code? I can't figure it out yet.

This is my MST based on a sample lambda dataset if it helps anyone either in programming it or finding where it is programmed.
