I just stumbled upon this announcement for a HTML5 'canvas' driver for
gnuplot:
http://www.nabble.com/New-terminal-driver%3A----set-term-canvas-tc21364389.html
The demos are at:

Howdy,
recently, Matthew Brett pointed out that reST supports a mode that's
very handy for writing tutorial-like documents that contain code
blocks including their output, and they can even be run as tests.
Here's a simple example with its corresponding source:
http://neuroimaging.scipy.org/site/doc/manual/html/users/analysis_pipeline.html
http://neuroimaging.scipy.org/site/doc/manual/html/_sources/users/analysis_pipeline.txt
and they can even use the MPL math support, as seen here:
http://neuroimaging.scipy.org/site/doc/manual/html/users/glm_spec.html
http://neuroimaging.scipy.org/site/doc/manual/html/_sources/users/glm_spec.txt
But we were thinking it would be great to have also plot support for
this, without being forced to use standalone scripts like in mpl's
current form of the plot directive. I unfortunately have to go now
and will be mostly offline for a week, but I just had a chat about
this with John, so I want to leave some context in here in case this
is of interest to you guys. If there's a discussion on the API, I'll
do my best to keep up, but I'm also cc'ing the nipy list so those
interested can pitch in (though we should keep the conversation to the
MPL list, where the plot machinery is implemented).
Cheers,
f

Thanks for the quick test and comments Andrew. I've made your suggested 
changes and attached a new patch.

Hi Gary, I have a couple comments:
1) No need for:
+ ax = fig.add_subplot(111)
+ ax.set_axis_off()
2) It's probably best to have maximum compatibility with imshow().
Therefore, use vmin=None and vmax=None as keyword arguments (rather than
clims).
Otherwise, I tested and it works for me.

Hi,
I've attached a patch against the mpl head in response to John's 
suggestion and helpful pointers on the users list. This adds a new 
function imsave to complement imread in the image module. I've also 
exposed it in the pyplot interface.
If this is presumptuous, feel free to remove it from the patch or ask me 
to remove it. This is my first contribution to matplotlib for a while 
and my first attempt at a patch like this.
Because I don't build matplotlib from source, I've done what testing I 
can without fully rebuilding matplotlib. I'd be reluctant to have this 
patch applied without someone else checking it first. It's pretty simple 
so applying it locally and running the demo file should be a good enough 
test.
thanks,
Gary Ruben
