//select all divs
d3.selectAll('div')
    //map some data to those divs, in order that they were found in the DOM
    .data(["hello","world","hi"])
    //and now do something to the divs with that data
    //perhaps, put the data in the divs
    //so this function param "d" is actually the data for that div
    .html(function(d) {
         return d;
    });
