what is an accessible network graph?

The feedback from our friends at the MIT Accessibiity office is:

"""
Networks, graphs, and to a lesser but still substantial extent trees, are very difficult to visualize via a speech interface (i.e. screen reader). I'm not sure how to approach this.

Since number of connections, and centrality seem to be important, you might create a table which can be sorted based on these numbers. It might have the node label in column 1 and a count of connections or centrality in column 2.

You could create a table such that the first column is a node, then all the rest of that row contain all nodes directly connected to it. You could combine these such that column 1 contained the node label, column 2 contained a connection count, and the rest of the columns contained node labels of those directly connected. Each directly connected node label could be a link to the row containing that node in column 1.

You may want to contact Mark [email protected]; he's their accessibility guru and he's extremely knowledgable (and sighted). He may very well have some more idea for you...
