|Re: IE question||Chris Hunter||10/8/11 9:00 PM|
I've been using an older branch of D3 that included svgweb support to get IE compatibliity. And it's worked but so far my visualizations have been largely static. So, I'd say that getting the animation working would be the riskiest piece.
You can check out my branch https://github.com/jugglebird/d3 to see if it works for you. If not, I'd be interested in what parts are working and what further changes might be needed.

|Re: IE question||Chris Viau||10/10/11 11:21 PM|
What if we could just hijack the d3 selection updating and appending to use another library for rendering (like dojo.GFX can use SVG, VML, canvas and SIlverlight)? It could look like:
var data = [100, 40, 20, 50];
var paper = Raphael(document.getElementById("viz"), 0, 0, 600, 400);
paper.circle(40, i*50+40, 10);
I can almost do it like this:

|Re: IE question||Chris Viau||10/18/11 9:57 PM|
I managed to make this work as a proof of concept:
var raphaelSVG = d3.select("body")
This pseudo-namespacing is ugly but it only required about 5 lines of code to make .append() and .attr() work with Raphael elements and attributes. If someone is interested, I can put the modified code on a repository.

Yes, a tutorial would be marvellous! Although I was hoping for a

going to be easy.

somewhat less sure about all this.)
|Re: IE question||Chris Viau||10/19/11 6:17 AM|
We all know the IE problem is IE itself. D3 is the most elegant library I know and closely follow HTML guidelines. I surely don't want its core to be all dirty with hacks just to make IE behaves. Making it work with IE9 is a start, but it only has 7% of market share yet according to W3Counter (September 2011), And the real problem is if we need to develop visualizations for business users. The bigger the business, the slower they update their browsers. The general solutions are:
-Develop without SVG. Pure HTML/CSS charts are more common than I previously thought
-Build the visualization server-side and just add interaction on the client side
-Use an abstraction over different rendering engine (Dojo.GFX, Raphael, Three.js)
-Use HTML5 Canvas. It's not well supported in IE but I think Ex-Canvas is doing a better job than SVGWeb to work in IE
-Use shims and polyfills, but I don't know of any that works easily for interactive stuff
-Make it static on IE and the full UX on real browsers
-Drop IE support
-Use Google Frame. That's probably the best solution
-Write two codes: SVG and VML. Do VML work in d3 out of the box?
Every hack to make d3 work with IE will also mean supporting IE on the rest of the code. I don't know if testing the d3 core in IE6 is a big priority.
But we still have to play with IE sometimes. What do you think is the best solution?

|Re: IE question||Nelson Minar||10/19/11 7:09 AM|
For this discussion it's important to separate IE9 from older versions of IE.
D3 should work in IE9. Also, IE9 supports SVG, so most of the visualizations people are doing should work. No need for a library like Raphael or svgweb. IE9 is the least well tested browser for D3, so there may be the occasional bug, but it should work.
D3 may or may not work in IE8 and older versions. However, before IE9 Microsoft did not support SVG. Since most people are using D3 to do SVG, that means their visualizations do not work in IE8. Realistically, they never will. svgweb in theory might work but I don't think anyone's demonstrated that being very effective. The bridge to Raphael is interesting, but honestly if you're going to do that why not just use Raphael natively? (D3 does not itself require SVG; you can use it to manipulate any DOM. But in the past, D3 has had some bugs related to IE8's APIs and I dont't think there's much enthusiasm for fixing them.)
Summary: IE9 good. IE8 and before, bad.
|Re: IE question||wimdows||10/19/11 8:16 AM|
Wel, it is not my aim to make graphs for business people, but for news
media. Unfortunately the people working for these media are just as
conservative when it comes to browser preferences. They don´t like it
very much that D3 wont work on older IE versions, so they will want
guarantees everything works fine in IE9. I fully agree with the no-
hacks-wanted argument. (So, screw IE8.) But I would sleep a lot better
if I could promise that full IE9 compatibility, no holds barred.
So, it sure would be great to have some sort of checklist.

This is less messy than my intrusive approach. Maybe we should concentrate on these kind of interoperability we could have with Raphael, like your line generator example. It can help improve D3 instead of pulling it back.
|Re: IE question||Jeff Pflueger||10/19/11 10:26 AM|
Glad you think so. Though it feels a bit messy to me.
And frankly, Raphael is a mess in comparison to d3! So my loyalties are
squarely with d3.
I will forge ahead then with playing with d3/Raphael interoperability

|Re: IE question||Nelson Minar||10/31/11 6:47 AM|
Nice writeup! I'm curious about the last bit of code; it looks like you use d3.svg.line() to create an SVG DOM element that's the line, and then use paper.path() in Raphael to render the line. Does Raphael magically convert SVG to VML behind the scenes?
|Re: IE question||Chris Viau||10/31/11 7:04 AM|
Thanks for trying this route. I wonder what's remaining of D3 after you remove all IE<9 incompatibilities. You used some helpers and generators. What else? My other experiments with various shims didn't gave much results. One thing is clear for me now, D3 will never let you append and reselect in the DOM on IE<9 in a data-driven way without a lot of effort.
|Re: IE question||Chris Viau||10/31/11 7:09 AM|
That's the whole point. Raphael is an abstraction over SVG and VML and use a syntax close to SVG.
I suppose you could write elements in the VML namespace with D3. But you would have to maintain to different code for graphic generation.
|Re: IE question||Chris Viau||10/31/11 7:11 AM|
And it don't create a DOM element but only the markup to create the path attribute that can also be used with Raphael.
|Re: IE question||Jeff Pflueger||10/31/11 8:25 AM|
No....Raphael requires a string in SVG format like this:
I can't find a way to generate this string in Raphael, and writing something to generate this string is a major undertaking.
But d3 has the method to create exactly this string:
d3.svg.line() - which impressively returns a string to draw a path in SVG format.
There are likely other d3 methods which return strings that can be used by Raphael.
For instance, the

|Re: IE question||Nelson Minar||10/31/11 1:37 PM|
Oh, I didn't know Raphael could work with SVG paths like that. It sounds like a useful adapter could be written on top of d3.svg that emitted those to VML by using Raphael's code to translate. Not sure that's a good idea, but it might work.
|Re: IE question||Chris Viau||10/31/11 1:49 PM|
Raphael don't translate SVG into VML like some shims can do. It translates an abstract syntax close to SVG into SVG and VML, So integrating D3 with Raphael requires using this abstract layer (like using attr() instead of setAttribute() or setAttributeNS()). It can be done, like I said earlier on this thread. I will try to share my code soon, as previously requested.

In my opinion I think integrating with something like Raphael is the
way forward. The main reasons are:
- Browsers will always need shims to make the ALL work the same. This
is the main lesson from the browser history if nothing else.
- This also means new platforms such as mobile phones and god knows
- Having some sort of abstraction layer means your code is more
portable. Say you want to port it to some offline application. Ideally
you solve a problem once and reuse everywhere. If your tied to a
particular implementation on a particular platform your limiting
Raphael uses something like the Abstract Factory design pattern
(http://en.wikipedia.org/wiki/Abstract_factory_pattern) so the
underlying implementation is behind a common interface. You might so
this with Raphael so that you can swap it out in the future for
something else just by writing an adapter interface to the new low
So you have a d3.line() method that just calls the d3.adapter.line(),
where adapter could be an interface to Raphael or dojo.gfx or TCL or
I have just found this lib today but maybe it wouldn't be so hard
(just boring) to abstract all the lower level calls to an Adapter
class and then write a Raphael implementation of this...?
might have a quick sniff....

Have you tried using svgweb by putting the d3 code and <script> tags inside a blank svg file instead of in the HTML? This bypasses the whole browser -> plugin DOM issue since d3 is only running inside the svg.
|Re: IE question||Chris Viau||11/16/11 12:21 PM|
Can you give it a try? On my side, I will experiment with the .select() function argument with Raphael. If the same thing was possible with .append(), it would be a good start. But if svgweb could work, the problem would be nearly solved.
|Re: IE question||Daniel Holth||11/16/11 1:10 PM|
Square should turn green. I couldn't get it to work in svgweb (not included in the gist, obviously). Unfortunately svgweb doesn't support anything but inline scripts inside svg, so d3 and my script are CDATA. I don't know how to debug it.
For non-svgweb purposes, <script> inside the SVG is awesome. Especially if you draw part of the chart in a vector graphics program.

I've started to work on my own library that sit on top of Raphael and

more OOP focused . I might also make the core rendering (not
interaction) work in Canvas as an exercise to make sure i keep lower
API interface platform independent.
At the moment I only need a line chart so I'll start with this and
