Get Attributes of HTML 5 Circles in Javascript


element.value; gets the value of a plain JavaScript object, not a jquery object.

$('circle').data('cx'); gets the value of the attribute data-cx="" or a value setted previously with the method $('circle').data('cx', 'whatever');

To fetch the cx and cy values, use :

var x_val = $('circle').attr('cx');
var y_val = $('circle').attr('cy');

UPDATE:

to iterate into multiple circles :

var x_val, y_val;
$circleArray = $('circle'); //get all circles

$circleArray.each(function(idx, el){//go through
each circle

  x_val = $(el).attr('cx');//get cx
  y_val = $(el).attr('cy');//get cy

  $('#result').append(idx+': '+x_val+' /
'+y_val);//here: print the values, but replace
this with whatever you need
});

How to Uniformly distribute svg circles in d3

As you've done for r, you can supply functions that act on each element in your dataset and return the desired value. I recommend using scales for x and y as well as r, and renaming them so you can tell them apart. There are also some great color scales. Your radius scale should be
