The support of the plugin company gave me following answer to my request of such a function: Of course you can write your own script for this. It would probably make sense to implement your own bulk edit function. Here () is the basic class and here () is an example implementation for downloading the labels. As I said, I just want a simple list of the shipments I picked in the list and bulk export them by clicking a menu entry on the dropdown list (see attached screenshot).

In the CSV for each date, every node has a specific color and size. I've attached a sample html file that draws the network graph as well as a sample picture of what it should look like. The structure of the CSV is not important, if there is a better way to feed the data it can be changed. The most important thing is for the network graph to animate over a range of dates and for each node to be able to change size and color. I should be able to switch the CSV with a new one and animate over a new set of nodes with unique parents, names, sizes, and colors.
