Answer 1

If you are injecting this into an HTML page (webpage), then you can include markup inside the text function.

var countryHeight = d.properties.value;
var countryName = d.properties.name;
p.text(function(countryHeight){return "The Average Height of Men in <b>" +  d.properties.name + "</b> = " + d.properties.value})
    .style("color", "red")
    .style("font-size", "150%");
