I am trying to reproduce and combine the D3 v3 Hierarchical edge bundling tree-map with the D3 v4 Zoomable Tree-map. I'd like to transfer the code logic that draws the link lines to the zoomable tree-map. I'm currently having difficulty finding the D3 v4 equivalent implementation of "d3.layout.bundle()". I have tried d3.bundle() but that just simply fails. I have tried simply copying the v3 line "var bundle = d3.layout.bundle()" but this also fails when referencing v4 library, with the error "Cannot read properties of undefined (reading 'bundle')"
Where as D3 v3 d3.layout.treemap has been ported to d3.treemap, there does not seem any direct equivalent for d3.layout.bundle.

I wonder if it is possible to use d3.v4 and d3.v3 at the samme time by renaming the global object d3 for example? I swchited to v4 but I need to merge a v3 and v4 project. I would like to rename v4 and use it independently. Is it possible?
Thanks
I've just started learning D3. It's at version 4 now and unfortunately most of the tutorials and examples online are of version 3.
I'm trying to create circles. But can't seem to get the attr method to work. I've created fiddles, simplified to render just one circle;
D3 v3 : https://jsfiddle.net/pratheepraj/595rrqc2/
D3 v4 : https://jsfiddle.net/pratheepraj/Ldokhq2e/2/
As you can see the exact code works in v3 but not in v4. In v4 if you inspect the element, the circles get created but the attributes are not set. Could u guys point out what should be changed for v4.
In D3 v4 you have two options:
Use .attr with a single attribute (see working example here: https://jsfiddle.net/yxprgokp/1/)
Use .attrs with attributes as an object, and an extra plugin to do that (https://github.com/d3/d3-selection-multi):
This module is not included in the default D3 bundle for parsimony’s sake: the single-value methods such as selection.attr are recommended for most users, as there is little benefit to the shorter syntax provided by these convenience method.

i'm just newbie in data visualization, but i must try to visualize for some data
i find the combo-multi-axes with highchart.js (http://www.highcharts.com/demo/combo-multi-axes), it's look perfect to me, but i want make it using d3.js, and i try search referrence for how d3.js can build it, but stil not found
How d3.js can build same like http://www.highcharts.com/demo/combo-multi-axes ?
I work on a d3js project and I saw some tutorial with append("g") and other with append("svg:g") without getting the difference between both.
In the very early days of D3 you were required to use the svg:g syntax because of the way SVG elements are appended to the DOM. Later versions of D3 don't require these "hints" to insert SVG elements, so the proper way to do this now would be with a simple g.
The technical details behind this are rather dull, SVG requires a namespace, so when you insert or manipulate SVG elements you use document.createElementNS('a', "http://www.w3.org/2000/svg) white plain HTML uses document.createElement('a'). Since D3 can manipulate both SVG and HTML d3.append('svg:a') was a way of saying this is an SVG anchor.
I got an answer on d3js API, its a namespace question. In svg:g, svg is the namespace (optional).
My fault, sorry i must better read API
Is there a jQuery plugin for displaying Dot files live in the browser as specified here?
I've seen a proof of concept at Visual Politics, but it doesn't seem to fully support the Dot language as even -- doesn't display correctly.
Any libraries out there I could have a look at for this?
I need to implement network graphs in the browser from dot files loaded via Ajax (rather than server side generated PNGs)
Check out Canviz: http://code.google.com/p/canviz/
Demos are located here: http://www.ryandesign.com/canviz/
As I was looking for the same answer, I found "viz.js" providing a java script version of GraphViz for DOT (see https://github.com/mdaines/viz.js).
Using this, I build myself WP GraphViz, a plugin for WordPress (see http://wordpress.org/plugins/wp-graphviz/).
I've been working on this for almost a week.
There are three different implementations:
1.Render svg in simple js, no needs install of graphviz
jquery.graphviz.svg https://github.com/mountainstorm/jquery.graphviz.svg
jQuery plugin to make Graphviz SVG output more interactive and easier to navigate. Makes it easy to have features like:
Highlight nodes/edges
Zoom in/out
Graph navigation - select linked nodes
Fancy UI tooltips; bootstrap supported out the box
Move things forward/back in the graph
Have a look at the demo: https://cdn.rawgit.com/mountainstorm/jquery.graphviz.svg/master/demo.html
2.Based on d3.js
<https://github.com/dagrejs/dagre-d3> d3.js + dagre
<https://github.com/dagrejs/dagre> pure js library
or:
<https://github.com/magjac/d3-graphviz> d3.js + graphviz c++ build
<https://github.com/hpcc-systems/hpcc-js-wasm> build graphviz 2.47
3.server side call graphviz to generate svg file.
