D3 - Dougnut Bubble Pie Chart
I am trying to create a merged pie/bubble chart. -- looking for a starting bubble chart base - maybe this one. http://jsfiddle.net/xsafy/ ^ need to cluster these bubbles - maybe s
Solution 1:
This is as close I have got so far.. I've merged the two charts together as such - although there is a bug still trying to update the bubbles -- at least get them to scale/morph/move/animate. Ideally I want them to stick close to their group segments..
here is the fiddle. https://jsfiddle.net/tk5xog0g/1/

I thought I will try and first plot mid dot points on the arcs -- and maybe from THOSE -- start to get a batch of zone coordinates to master control the coloured bubbles.
I've been trying to follow this -- How to get coordinates of slices along the edge of a pie chart?

/*placing mid dots*/var midDotsArrayCooridnates = [];
slice
.each(function(d) {
x = 0 + (radius * 0.85) * Math.cos(d.startAngle);
y = 0 + (radius * 0.85) * Math.sin(d.startAngle);
var obj = {
"x": x,
"y": y
}
midDotsArrayCooridnates.push(obj);
});
$.each(midDotsArrayCooridnates, function(index, value) {
var dot = doughpie.select(".slicedots").append('circle')
.attr('cx', value.x)
.attr('cy', value.y)
.attr('r', 5)
.style("fill", "red")
.attr('class', "ccc")
});
