You can also do it this way and execute the callback when the script has loaded to use it.

D3 is probably the ultimate in charting tools and is HUGE i agree but a lot of that is the data manipulation routines, cross browser, legacy browser support stuff... Don't we potentially want all them too?

Making it a jquery plugin doesn't actually have that much overhead but i think they could/should further split the sections into sub plugins so that you can pick and choose which you require...

Its only 135kb minified though - not much or any bigger than 1 decent sized image - what we need to do in xenith is enable on-demand loading/background pre-fetching of these libraries i think and then there isn't an issue...

See here though for others http://techslides.com/50-javascript-charting-and-graphics-libraries/

I was actually wondering whether we should just make the editor code into jquery plugins which leverage the power of jquery chaining and oop in a sense, so something like:

$('#treemenu :nth-child(6)').insertBranch('...').bind('click', function().... Etc

Easy to do, maintain and read...

It is a plugin, but you could link the raw GitHub stuff to save space.

I think the jquery in XOT could be moved into a library into which D3 could be added

I've got two D3 plugins half developed, but I've just bundled the JS in

There are some really nice examples on their site. I think it’s abit more than I need: it seems to be a whole jquery like plugin, rather than just the charting stuff.

This is one example where being to load libraries from a CDN would be good, because then people can choose. I don’t know if you can make the charting setup FWS for anything but the simplest charts, which we already have.

After equations though, academics would make a lot of use of charts. I suppose they can do them as images, but it’s a bit of a hassle.

The ability to show a range of charts would be a good addition to the site template, and the toolkit, it would complement the MathJax stuff nicely.

Does anyone have any recommendations?
