Greetings,

I am looking for information, tips, and pointers on writing a component for visualizing text data in Galaxy. In particular I would like to use Brat (http://brat.nlplab.org/embed.html) which can be embedded in web pages/apps. The “Implementation Details” section on the Learn/Visualization page (https://wiki.galaxyproject.org/Learn/Visualization#Implementation_Details) hints at exactly what I want to do:
- use AJAX to fetch JSON data.
- use a Javascript client to draw the data

I can do both of the above steps, I am just not sure how to wire Brat into Galaxy. All of the documentation I can find about visualization covers installing existing Genome visualization tools and nothing about how to adapt an existing Javascript client to work in Galaxy. I am hoping someone can sketch out the basic steps I need to accomplish before I spend too much time grepping through the Galaxy code base.

Cheers,
Keith
