Does anyone know if there is any available code for an interactive web-based ideogram viewer? It would likely be written in javascript. I want to show an ideogram that dynamically displays some annotations (genes related to a phenotype search, for example).

I have found [this ideogram viewer][1], but it is under copyright and the code has not been made available. There is also [Phenogram][2], which looks nice, but is unfortunately only static images. I want to integrate this into a tool I'm building, so existing web-based genome browsers that have ideograms are not sufficient.

Thanks.

I just came across this, and got it up and running quite easily:

Pretty much exactly what I was looking for in my original question.
