nvd3 line plus bar chart with variable circle sizes - nvd3.js

Question

I am using nvd3 line plus bar chart and am trying to change the size of the circles in the line chart. (Each circle with a different radius on the line chart)
To make the points visible on the line chart, I used the following CSS code -
#test-plot .nv-linePlusBar .nv-point
{
fill: #ff5f00;
fill-opacity: 0.6;
}
I am calling the addRadius method after the chart is drawn.
function addRadius() {
for (var i = 0; i < plotdata[0].values.length ; i++) {
var rad = parseFloat(plotdata[0].values[i].r);
$('#test-plot .nv-point-' + i).attr('r', rad);
}
}
setTimeout(addRadius, 500);
This code worked for older version of nvd3 but not version 1.8.1 or higher.
I saw some solutions here but they do not work for the latest versions of nvd3.

Triy with the following CSS:
.nvd3 .nv-groups .nv-point {
stroke-opacity: 0.5 !important;
}
and change the selector in the addRadius() function:
function addRadius() {
var dt = data[1].values;
console.log(dt, dt.length)
for (var i = 0; i < dt.length; i++) {
// just an example
var w = 20 * dt[i][1] / 600;
$('.nvd3 .nv-groups .nv-point-' + i).css('stroke-width', w);
}
}
Check this snippet:
var data = [{
"key": "Quantity",
"bar": true,
"values": [
[1301544000000, 2000],
[1304136000000, 2500],
[1306814400000, 1800],
[1309406400000, 2100],
[1312084800000, 2100],
[1314763200000, 2800]
]
}, {
"key": "Price",
"values": [
[1301544000000, 348.5075, 20],
[1304136000000, 350.13, 30],
[1306814400000, 347.83, 10],
[1309406400000, 335.67, 5],
[1312084800000, 390.48, 40],
[1314763200000, 384.83, 10]
