Access graph properties in Spotfire

I have a Spotfire file and I am trying to automatically extract some info from its contents. I do not have any preferred way to do this, but I understand that IronPython is probably the way to go.

This is the furthest I got:

page = Document.Pages[0]
for vis in page.Visuals:
    print(vis.Title)

This outputs the title of all graphs/visuals. However, I am at a loss about how I could extract other info, like Graph type or x-axis title. I tried to find my way through the API, but have been unsuccessful so far.

My Spotfire build version is 7.6.1.7. Any help would be greatly appreciated.
