One approach to the animation issue is to use CSS transitions. This way your code is just responsible for setting the new value (which can be done by Om/React or any other approach) and then the browser is responsible for making the animation happen appropriately (and efficiently, with full hardware acceleration, etc). This is, for example, the approach suggested by Kevin Lynagh for use with his awesome C2 library which is like D3.js for ClojureScript and which comes with no built in animation support whatsoever: https://github.com/lynaghk/c2 I'm not a front end developer and so I don't spend too much time on this type of stuff, but when I have had occasion to use it, I found this approach much more pleasant than oldschool jquery style approaches to animation.
In The Case for React.js and ClojureScript

I agree that using it with existing frameworks is not that useful and probably a bad move. I'm using it a bit with jQuery. The real benefit I see are with some of the new ClojureScript libraries. My feeling is that we wont see many ClojureScript frameworks as thats not really the Clojure way. I'm struggling myself with finding the right way of using ClojureScript, but it's early days yet and whatever experimentation we do now will probably guide the way. There are interesting patterns happening now though such as the use of atoms for data binding as is used in Reflex/C2 https://github.com/lynaghk/reflex https://github.com/lynaghk/c2 I'm still looking for good ways of doing routing in single page apps.
In Marrying ClojureScript and JS Frameworks – Knockout Edition

Thanks! It's an SVG image that is built with C2[1], a ClojureScript library that provides some handy tools for working with svg. After the image is done rendering, there is a callback that draws a hidden tooltip next to each of the points. The callback also puts all of the points into a kd-tree for efficient nearest neighbor searches. When a mouse hovers over the graph, the point nearest the mouse tells its tooltip to display itself. Other people have made really excellent graphs using d3.js. Check out their examples if you want to be impressed: https://github.com/mbostock/d3/wiki/Gallery I've also seen a lot of people using HighCharts. You can probably get these out a lot faster than building one using a library like d3 or C2. You'll also get support for browsers that don't render svg for free. Here's a good example: https://coinbase.com
