I'm a noob and trying to implement a search method for a diagram.
The diagram is a chord diagram and was mostly adapted from here:
http://bl.ocks.org/mbostock/1044242
And the search function was taken from here:
http://mbostock.github.io/protovis/ex/treemap.html
My problem is that when it reads my file it interprets the text as: [object SVGTextElement] and so the only hit I have for my search is if I search [object SVGTextElement].
This is my entire code:

The input is bla3.json and looks like this:
[{"name":"A.Patient Intake","imports":["E.Name","C.injury","E.DOB","E.Email","Progress","B.Obtain Brief Medical History","Perform Physical Exam","Perform Subjective Patient Evaluation"]},
{"name":"C.injury","imports":[]},
{"name":"E.Name","imports":[]},
{"name":"E.Email","imports":[]},
...
I didn't put the whole thing but it shouldn't matter...
My purpose is of course to have a search function that I could type, for example, "Patient Intake" and it will highlight that chord (or just the name):
Any ideas of how to go about this?
