Wow, I was just going to ask this as well. Have recently been in touch with
some of the dojo people, specifically the http://openrecord.org people. We
were chatting about integrating GIS functionality in to it - they have a
number of ways to display data through charts, and on a map would make a lot
of sense. OpenLayers is an obvious choice for that as both are pure
javascript.
Their vector support looks quite nice:
> The new Dojo 0.4 release includes a dojo.gfx 2D vector > graphics
library, which renders natively to browsers as SVG or VML > (which means it
supports both Firefox and IE, as well as others).
> Having the new dojo.gfx library should make it fairly easy to write a >
tool that would let a user draw lines and shapes on top of a map, and >
then pan and zoom those drawings whenever the user pans and zooms the >
map itself.
