Bring up a modal when a marker is selected?

[carterw]

I'd like to be able to have a modal pop up when a marker on a chart is clicked, and be able to customize the contents of the modal based on the marker data.

I'm able to capture the event when the marker is clicked, but it isn't clear to me how to generate the modal, dynamically initialize the content, and show it. For a DOM element like a button, you can have a data-toggle='modal' and a data-target='#myModal' attribute. Can you do something like that with a marker?
