Really nice tutorials, the background music is nice too, the pace is pretty fast as well which is something you don't usually see on tutorials, however this is way better than a slow presentation which makes it unbearable to watch after a point. Never used d3.js before, however i really enjoyed the tutorials. I ended up watching 3-4 of them and got interested on the library.
The only negative comment i guess i can make (as a suggestion) is that on some videos the music is a bit high which ends up overlapping with your voice.
thanks, this means a lot because that's exactly what i was going for!
i also figured out how to use screenflow better like 5 videos into the process, so hopefully the sound will be better balanced from now on.
Very cool! D3 was intimidating to me, and personally screencasts similar to this are helpful when trying to get a broad overview of a library. Even better, all the code for each video is provided with a live code editor.
i haven't played too much with raphael.js, but it seems convenient for vector drawing, and i hear its pretty quick to get started with. d3 really shines when it comes to data-driven graphics, and it's a much broader set of tools for data visualization in the browser. it also has a steeper learning curve, which i'm trying to alleviate with these videos!
