Have you ever asked how to change the size of the text displayed on elements of a D3JS plot so far?

If you want to change the size of text on D3JS graphs, please add this .style("font-size", "1.5em")to the elements in question.

var gs = svg.selectAll(".arc")
   .attr("class","arc"); //all arcs

And then adding the following statements

  .attr("transform", function (d) {
       return "translate(" + arc.centroid(d) + ")";
  .attr("text-anchor", "middle")
  .attr("fill", "white")
  .attr("font-family", "sans-serif")
  .style("font-size", "1.5em")
  .text(function (d) {

Hope this small tip will help you very much in your work.

Happy coding!
