Display node attribute on mouse event in WebGl

[qdelettre]

Hi,

I am trying to understand the library and webgl. I would like to display node text attributes on mouse over event, in webgl.

The use case would be that : user put the mouse cursor on a node, the text attribute of a node appear over it. The text disappear as the cursor is no longer on the node.

How can i have access to the canvas and its context ?
Can i use the fillText function to draw the text ?

Thanks
