Other Word Tree Configurable Options?

[David Jea]

Hi,

For the word tree, https://developers.google.com/chart/interactive/docs/gallery/wordtree,

are there more than listed configurable options?

For example, backgroundColor is used in the example, but it is not listed  "Configuration Options" table,

so I wonder if there are more options that can be set.

More specifically, I am looking for if there is 'title' option like you have in other charts.

Thank you,
