Simplicity was definitely the prime motivator when I chose to write the graphing code from scratch for howmanyleft.co.uk (instead of using flot or similar). I also wanted something that worked reasonably well on mobile and desktop. Morris.js scales relatively well to small screens, and it also supports touch events. Immediate improvements are likely to be better date handling and x-axis labelling (really they're both fixes rather than enhancements). Development so far's been driven by my rather specific requirements for howmanyleft. I'd not initially intended to release it, but several requests from other interested developers prompted me to stick it up on github with a quickly hacked-together project page. I'm keen to see what other devs would like to do with it!
