Div for tooltip

Hi !

I ‘ve tried desperatly to find how to make my code working with a div for my tooltip.

// Define the div for the tooltip
var div = d3.select(“.wpd3-71-3”).append(“div”)
.attr(“class”, “tooltip”);

I think that i’m not calling the right thing but i don’t know how to write the code to make my tooltip work on my wordpress blog !

To see what the chart look like : http://bl.ocks.org/dyorama/d368d3137fd6abb48fa3
