I've created a simple library for dealing with tooltips in d3 if anyone is interested.
@caged Thanks! this is really helpful +1
If anyone else is getting event is not defined or similar add d3. to the events:
return tooltip.style("top", (d3.event.pageY-10)+"px").style("left",(d3.event.pageX+10)+"px");
svg:title does work as a tooltip in Firefox 37 and Chrome 42. That's good enough for me! :)
Can we apply anything instead of
.style("left", (d3.event.pageX - 34) + "px")
.style("top", (d3.event.pageY - 12) + "px");
because when i use this the tooltip is not displaying in its position correctly.....
Below two things also not working:
1)
.style("left", d3.select(this).attr("cx") + "px")
.style("top", d3.select(this).attr("cy") + "px");
.style("left", dx + "px")
.style("top", dy + "px");
Can i have good solution for this?
brilliant and simple, thanks!

Nice example. But if you try this on firefox your tooltip is under the circle. You should change event.page to d3.event.pageX/Y like in the example from pixeline.
