Slow performance in Firefox for D3 force layout

Slow performance in Firefox for D3 force layout - javascript

I've created a force-layout using D3 (see image below). However, it runs very slowly in Firefox, whereas it works perfectly fine in Chrome. I'm debugging it using a local server and browsing at http://localhost:8888/. It's might be due to the following message in the Firefox console, but accordingly to the comments that's unlikely. Can someone pinpoint the performance issue and give me a hint on how to resolve it?
mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create

EDIT
The root cause of the problem was document bloat caused by failing to remove outdated linearGradient tags in the defs section of the
HTML. This was only happening in Firefox because of what it returns
in response to getPropertyValue in it's CSSStyleDeclaration
interface (which is called by d3 in selection.style()). The value
returned is of the form
"url("http://localhost:88888/index.html#line-gradientXXXXXX")
transparent", compared to "url(#line-gradientXXXXXX)" in the other
browsers. Since the id was not properly extracted by the OP,
linearGradient tags ear-marked for deletion were not found and not
deleted, causing them to grow in number. The problem is avoided by
using unique indexing, already available in the data, to label the
linearGradient tags.
As per my comments above, I managed to solve the Firefox problem by making the following changes:
Eliminate redundant calculations in the forEach sections in tick and applyGradient.
Using well-formed d3 to manage the defs. It was probably fine how it was, it just took me a while to realise how it was done but, I changed it to standard d3 patterns which will manage updating and changing data properly. This line is particularly sensitive...
var new_gradient_id = "line-gradient" + getRandomInt();
this works better...
var new_gradient_id = "lg" + interaction_type + d.source.index + d.target.index;
Applied standard d3 patterns to managing the callLink and textLink sections in CreateVisualizationFromData. Using these patterns it updates properly and manages changing data.
After making these changes, the speed problems in Firefox disapeared and it is now the same in all three major browsers in terms of speed. It looks better in Chrome though. Some experimenting would be in order to determine exactly which changes are critical, but there was definitely a problem with deleting the linearGradient tags. These were not being properly deleted in FF and massively bloating the DOM. I think this is probably what was causing the problem.
The other changes I made were just stylistic to make it easier for me to understand.

How to create a dashed line with arrows on each dash in d3?

How to make a line from arrows like a dashed line but somewhat like this "> > > >" for direction of the flow. I am trying to connect nodes via lines but my nodes have to resizable rectangles and it hides the arrowheads , which is why I am looking for such arrow(ed) line. Specifying arrow in the middle could also solve the problem but attr("marker-middle", "url(#arrowhead)") does not work in my code.

I think this is what you want, this code snippet based on this bl.ocks.org snippet and it meant to be animated by I removed the requestAnimationFrame call from the update function.
regarding your original issue with nodes hiding the arrow, you can use refX and refY attribute on <marker> to change its offset.
var path = document.querySelector("path"),
totalLength = path.getTotalLength(),
group = totalLength / 20,
start;
var arrowheads = d3.select("svg").selectAll("use")
.data(d3.range(20).map(function(d){ return d * group + 50; }))
.enter()
.append("use")
.attr("xlink:href", "#arrowhead");
path.style.strokeDasharray = "50," + (group - 50);
requestAnimationFrame(update);
function update(t) {
if (!start) {
start = t;
}
var offset = -group * ((t - start) % 900) / 900;
path.style.strokeDashoffset = offset;
arrowheads.attr("transform",function(d){
var l = d - offset;
if (l < 0) {
l = totalLength + l;
} else if (l > totalLength) {
l -= totalLength;
}
var p = pointAtLength(l);
return "translate(" + p + ") rotate( " + angleAtLength(l) + ")";
});
//requestAnimationFrame(update);
}
function pointAtLength(l) {
var xy = path.getPointAtLength(l);
return [xy.x, xy.y];
}
// Approximate tangent
function angleAtLength(l) {
var a = pointAtLength(Math.max(l - 0.01,0)), // this could be slightly negative
b = pointAtLength(l + 0.01); // browsers cap at total length
return Math.atan2(b[1] - a[1], b[0] - a[0]) * 180 / Math.PI;

How to stop text transitioning off the screen

I have a visual of a two ringed pie chart.
What I'm building is the following:
- if a sector's radians are too small for the specified text then the text is hidden. This is done and seems to work ok
- if text is hidden then a label should appear outside the pie. This is also done when the visual is initially rendered.
When the radio button is pressed the labels outside the pie should transition accordingly. I've attempted the transition and slowed it to 3500 and these labels are just slowly transitioning off the screen.
How do I fix this transition?
The snippet I've added to try to create the transition starts at line 241:
var arcs2 = svg.data([json]).selectAll(".arcG");
arcs2.data(partition.nodes)
.transition()
.duration(3500)
.attr("transform", function(d) {
var c = arc.centroid(d),
x = c[0],
y = c[1],
// pythagorean theorem for hypotenuse
h = Math.sqrt(x * x + y * y);
return "translate(" + (x / h * labelr) + ',' +
(y / h * labelr) + ")";
})
.attr("text-anchor", "middle");
svg.selectAll(".theTxtsOuter")
.text(function(d, i) {
if (d.name === 'root') {
return;
} else if ((d.depth === 1) && (d.dx < (d.name.length * 0.15))) {
return d.name;
} else if ((d.depth === 2) && (d.dx < (d.name.length * 0.1))) {
return d.name;
} else {
return;
}
});
This is a plunk of the working(!) visual:

When you initially position them you are transforming the text elements. When you transition them you are positioning the outer g elements. These causes conflicting transforms. Use:
arcs2.data(partition.nodes)
.select('text') //<-- apply on child text
.transition()
.duration(3500)
.attr("transform", function(d) {
...
});
Updated plunker.

Animate objects in force layout in D3.js

I need to create a data visualisation which would look like a bunch of floating bubbles with text inside of the bubble.
I have a partially working example which uses mock data prepared here:

min = 0;
}
return min + Math.floor(Math.random() * (max - min + 1));
};
// mock data
var colors = [
{
fill: 'rgba(242,216,28,0.3)',
stroke: 'rgba(242,216,28,1)'
},
{
fill: 'rgba(207,203,196,0.3)',
stroke: 'rgba(207,203,196,1)'
},
{
fill: 'rgba(0,0,0,0.2)',
stroke: 'rgba(100,100,100,1)'
}
];
var data = [];
for(var j = 0; j <= 2; j++) {
for(var i = 0; i <= 4; i++) {
var text = 'text' + i;
var category = 'category' + j;
var r = random(50, 100);
data.push({
text: text,
category: category,
r: r,
r_change_1: r + random(-20, 20),
r_change_2: r + random(-20, 20),

// animate
var interval = setInterval(function(){
// moving of the circles

}, 5 * 1000);
However I am now facing problem with animation. I cannot figure out how can I animate nodes in force diagram. I tried to adjust values of the data object and then invoke .tick() method inside setInterval method, however it didn't help. I am utilizing D3 force layout.
My questions are:
How to make the bubbles "float" around the screen, i.e. how to
animate them?
How to animate changes of circle radius?
Thank you for your ideas.

Actually, I think this one feels nicer...
Key points
Charge set to 0, friction set to 0.9
Schedule parallel transitions on the radius and line in the timer callback
Use the dynamic radius for calculating collisions
Use a transform on the nodes (g element) to decouple text and line positioning from node position, adjust the transform x and y, only in the tick callback
Remove the CSS transitions and add d3 transitions so that you can synchronise everything
changed this r = d.rt + 10 to this r = d.rt + rmax in the collision function to tighten up the control on overlaps
Closed loop speed regulator. Even though friction is set to 0.9 to dampen movement, the speed regulator will keep them moving
Use parallel transitions to coordinate geometry changes
Added a small amount of gravity

l = (l - r) / l * (1+ alpha);
and then use an alpha of about 0.05
No need for gravity or charge in my view, the only thing I change is to set friction to 1. This means that velocity is maintained, but if your clients are getting motion sick then knock it back to 0.99.
EDIT:
changed to a slightly softer and more correct collision model
l = (l - r) / l * (1/2 + alpha);
Also added a little gravity to make it "cloud-like" and friction (see above)
CSS transitions
I also tried to use CSS transitions but support seems patchy to say the least on SVG elements.
Transition works on circle radius but not on line in chrome (45.0) and Opera
In IE 11 and FF (40.0.3) none of the CSS transitions work for me
I would be interested in any feed-back on browser compatibility as i couldn't find much on the internet about this.
I experimented with velocity.js on the back of this and I think I prefer it for the transitions.

D3 force layout works in Chrome, but not in Firefox

I've created a force-layout using D3 (see image below). However, for some reason it does not work in Firefox, whereas it works perfectly fine in Chrome. There's no errors in the Firefox debugger, but it only shows me a single line in the right side of the browser (as if the force layout never updates). I'm debugging it using a local server and browsing at http://localhost:8888/.
I've been looking at different posts regarding compatibility on stackoverflow, but I can't seem to find anything related to my code. If someone could give me a header on what to debug first, that would be great!
Edit: I've included links to the data as well as the csv-files in plain text at the bottom of my post. Data and code: https://www.dropbox.com/s/ksh2qk1b5s9lfq5/Network%20View.zip?dl=0
Here's the output from the Firefox console:
mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create d3.js:553:4
SyntaxError: An invalid or illegal string was specified d3.js:562:0

The syntax error is with this line:
defs.select(current_gradient).remove();
But above that is the real problem. Replace:
current_gradient = current_gradient.substring(4, current_gradient.length - 1);
With:
if (current_gradient.match("http")) {
var parts = current_gradient.split("/");
current_gradient = parts[-1];
} else {
current_gradient = current_gradient.substring(4, current_gradient.length - 1);
}
When you originally set the current_gradient in Chrome, it is set to "url(somevalue)" whereas in Firefox is it set to "url(fullpath/somevalue)". So you need to remove all the path info, not just the "url()" bit. Splitting the slash and taking the last value from the split is probably the easiest way to do that.

Look at this piece of code, you should be able to add the depth for each ring. You should know the max depth of the layout and that gives you your outer ring.
var path = vis.selectAll("path").data(nodes);
path.enter().append("path")
.attr("id", function(d, i) { return "path-" + i; })
.attr("class", function(d) { return "ring_" + d.depth; }) <--- add this line
.attr("d", arc)
.attr("fill-rule", "evenodd")
.style("fill", colour)
.attr("title",function(d)
{
return d.depth ? d.desc: "";
})
.on("click", nodeClicked);
Just in case you find some useful ideas here: http://protembla.com/wheel.html some unfinished viz I played with when I was just learning d3, so quality is not great!
