Use requirejs to load d3

[akre54]

d3 version 4.0 no longer exposes the d3 global (https://github.com/d3/d3/issues/2615) when in a requirejs environment (like Jupyter).

Instead of a <script> tag, you'll need to set up the path first:

requirejs.config({
    paths: {
        d3: 'https://d3js.org/d3.v4.js' // Or whatever
    }
})

And then later:

require(['d3'], function(d3) {
 // run d3 logic here. maybe set window.d3 = d3
})

Yes, this is exactly right. I've patched it, should now work in 4.x. Let me know if there are any issues.

Some more references: here, here, here, here.

actually I had to leave out the .js at the end of the d3 path because requirejs added it automatically and it was thus trying to call https://d3js.org/d3.v4.js.js which returns 404.

Code that worked for me in jupyter:

requirejs.config({
    paths: {
        d3: 'https://d3js.org/d3.v4'
    }
});

require(['d3'], function(d3) {
 window.d3 = d3;
});

Hi there,

I'm hoping someone can save me from a newbie error! I've tried the approach above but i still can't seem to load d3 v4. Only v3 :-(

I'm using Jupyter notebook v5.0.0 and py-d3-0.2.7.

Here's a screen shot - please let me know if you can spot anything wrong.

Many thanks in advance Ben

Run in your notebook:

In [1]: %d3 version

If you obtain an error then reinstall py_d3 with pip install py_d3 --update.

Hi, thank you for the quick response! :+1:

I tried the %d3 version command but got an error even after updating with pip (version is 0.2.7)

I believe that mondeja added the version functionality in his recent PR, and I haven’t pushed that to PyPi yet! Whoops.

You can either install from master (pip install https://github.com/ResidentMario/py_d3.git) or you can wait a couple of days until I get the new py_d3 version out on PyPi. ​

Fixes are now live in the newly-released 0.3.0! 🎉

@mondeja if you want to submit a PR with the additional blog builder API surface, now is the time. 😃

@bendavidwhite let me know if you have any issues after doing a pip install -u py_d3 to get the latest version.

Thanks @ResidentMario, I ended up downloading and installing the repo directly. It worked. Thank u!
